- bugfix: handle connection options w/o "backup" env var
Previously, ‘pg-conndefaults’ expected every option to have a
backup env var (e.g., option ‘#:host’ and env var ‘PGHOST’).
For later versions of PostgreSQL which no longer maintain this
1:1 correspondance, Guile-PG would segfault.
Now, in such cases, the value associated w/ the key ‘#:envvar’
in the alist returned by ‘pg-conndefaults’ is ‘#f’.
- planned retirement
- procedure ‘(database postgres) pg-getline’
- procedure ‘(database postgres) pg-getlineasync’
- procedure ‘(database postgres) pg-putline’
- procedure ‘(database postgres) pg-endcopy’
These procedures are obsoleted by ‘pg-get-copy-data’ and
‘pg-put-copy-data’. They WILL BE REMOVED by 2013-12-31.
Actually, the first two were originally -- in Guile-PG 0.41
(2011-09-29) -- planned to be removed by 2012-12-31.
Support has been extended for solidarity w/ the latter two.

- support for "make installcheck"
This does "make check" at its core, so the same env vars apply.
Obviously, you should do "make install" first for sane results.

If you have GNU tar, you can use "tar xf" and it will DTRT.
If not, you can use "xz -dc TARBALL | tar xf -" to unpack.
- bugfix: ‘pg-get-copy-data’ handles unspecified ‘async?’
Previously, if ‘async?’ was unspecified, it was incorrectly
interpreted as true (i.e., "not false"). Now, if unspecified,
it is interpreted correctly as false.
- testing slack for pre-8.1 ‘pg-client-encoding’
Previously, the types-table test was too strict when checking
the ‘pg-client-encoding’ return value, expecting "UTF-8" only.
Now, it accepts also "UNICODE", which is the norm for PostgreSQL
prior to 8.1.
- support for ‘make check KEEPD=1’
If you run "make check" many times, you can avoid daemon bounce
overhead by specifying ‘KEEPD=1’, which inhibits daemon killing.

[PBI] means "WARNING: potentially backward-incompatible".
- bugfix: ‘sql-quote’ translates backslash (#\\) to ‘\134’
Previously, backslash characters were passed through
unmodified. Now, they are translated to the string "\134"
(i.e., the four characters ‘#\\’, ‘#\1’, ‘#\3’, ‘#\4’).
- [PBI] ‘bytea’ stringifier outputs only one backslash
If the ‘bytea’ stringifier from ‘(database postgres-types)’ is
used standalone, this represents a BACKWARD INCOMPATIBLE change.
In the normal case, however, where the stringifier is used in
conjunction with ‘sql-quote’, this change is transparent.
- new (database postgres-qcons) proc: string-xrep
Some versions of Guile emit ‘\xXX’ to represent the octet with
hex value XX when constructing the external representation of a
string, for certain octets. Furthermore, some versions of
PostgreSQL cannot grok such escape sequences anyway. The new
procedure ‘string-xrep’ is like ‘object->string’ (for a string
arg) except that it explicitly emits the octet itself, except
for ‘#\\’ and and ‘#\"’, which are backslash-escaped as normal.
- ‘(database postgres-qcons) idquote’ no longer emits ‘\xXX’
Before, ‘idquote’ used ‘object->string’ internally, and thus
suffered from the problems described in the preceding NEWS
entry. Now, it uses ‘string-xrep’.
- ‘(database postgres-col-defs) validate-def’ more permissive
A column name may now be any symbol that does not contain
whitespace. Previously it was restricted to a symbol whose
constituent characters were alphanumeric or underscore.
This change makes Guile-PG less strict (in some sense) than
PostgreSQL, which imposes other rules. Overarching is the
recommendation from PostgreSQL to consistently use a "delimited
identifier" (aka "quoted identifier") rather than a naked name.
That's what ‘idquote’ and ‘string-xrep’, both used extensively
in Guile-PG, do. See section "Identifiers and Key Words" in
chapter "SQL Syntax" in the PostgreSQL documentation, for more
information.
- ‘pgtable-manager’ and ‘pgtable-worker’ likewise relaxed
These use ‘(database postgres-col-defs)’ procs and new proc
‘string-xrep’ internally, and thus benefit from the changes
mentioned in the preceding NEWS entries. Notably, table and
column names are less constrained. For example, see file
test/types-table.scm, proc ‘test-m2’.
[Probably "relaxed" is not as good as "strictness relaxed and
multi-byte-fu enhanced", but that does not fit on one line.]
- fake cluster created on-demand for "make check"
In addition to a fake installation, "make check" now also
creates a cluster under test/fake-cluster/ configured for
Unix-domain connections, and kicks/kills the daemon around the
actual ‘runtest TEST’ invocations. This means it is no longer
necessary to set env var ‘PGDATABASE’. In fact, that and env
var ‘PGHOST’ are now silently ignored, since ‘runtest’ clobbers
them internally.
If you previously tested Guile-PG against different PostgreSQL
versions by varying ‘PGDATABASE’, you now need to vary env var
‘INITDB’ instead, and zonk the cluster before the "make check"
invocation. Something like:
$(MAKE) delete-cluster
$(MAKE) check DEBUG=1 INITDB=/a/particular/initdb
in directory test/ would be fine. See README section "Testing".
- 0.42 | 2011-10-04
- bugfix: "make check" no longer clobbers installed file
For Guile versions that require a Scheme wrapper for .so loading
(i.e., Guile 1.8 and later), "make check" does a fake install w/
a ‘prefix’ in the build tree. Unfortunately, in Guile-PG 0.41,
that dir was not specified to the Scheme wrapper, resulting in
its installation under the "real" (as determined / set by the
configure script) ‘prefix’.
The system would reamin in this inconsistent state, with the
wrapper pointing into the build tree, until "make install", at
which point everything was resynchronized. Obviously, if you
never do "make install", the problem persists (silently, until
the build tree is deleted).
This has now been fixed. If you did a "make check" but NOT
"make install" of Guile-PG 0.41, the best way forward is to
configure Guile-PG 0.42 and then "make install; make uninstall".
- ‘pg-print’ now does ‘fflush’ after each operation
This probably kills performance, but it is safer, given Guile's
direct use of ‘write(2)’ et al.
- ‘pg-set-client-encoding!’ also accepts symbolic encoding
- 0.41 | 2011-09-29
- Bugs fixed
- Make ‘idquote’ special-case ‘*’ in second part.
was: (display (idquote 'a.*)) |= "a"."*"
now: (display (idquote 'a.*)) |= "a".*
- Call ‘string-append’ with strings, not symbols.
We no longer rely on this particular Guile 1.4 slack.
- Portability fixes (tested w/ Guile 1.8.7)
With the following (and other, non-user-visible) changes, "make
check" no longer displays "foo is deprecated" messages with
Guile 1.8.7. If you see them for your system, for either "make
check" or subsequent Guile-PG use, please report that as a bug.
- Don't do "defer/allow ints" for Guile 1.8+.
- Revamped Scheme object to C byte range for Guile 1.8+
Access to Scheme string representation was curtailed in Guile
1.8 (API available but deprecated), so all operations that pass
a C byte range to libpq functions now incur an extra conversion
step. The unfortunate user-visible result is performance loss.
- Planned retirement
- procedure ‘(database postgres) pg-getline’
- procedure ‘(database postgres) pg-getlineasync’
These procedures are obsoleted by ‘pg-get-copy-data’ and
WILL BE REMOVED by 2012-12-31.
- New fluid to control ‘(database postgres-qcons) sql-quote’
The fluid ‘sql-quote-auto-E?’ controls whether or not
‘sql-quote’ should check for ‘\’ (backslash) characters and
prefix an "E" in that case. This is relevant if you use
PostgreSQL 8.2+.
- New support for "hex format" in ‘bytea’ objectifier
PostgreSQL 9.0 introduces a more efficient "hex format" for
‘bytea’ output. This is now recognized and parsed, falling back
to handling the traditional "escape format" if not recognized.
- Doc improvements
- Fix omission: Document ‘pg-get-copy-data’ arg ‘async?’.
- Indices merged into one
- Builtin type converters listed and indexed
- Builtin type converter array variants listed
- For ‘make check DEBUG=1’, display the guile(1) invocation.
- Tested w/ latest server versions: 8.[01234], 9.[01]
Additionally, the entries in file test/OK now include the
associated Guile-PG version, and some include a subheading
"other pg" to list the precise server version numbers.

- 0.39 | 2010-01-11
- Dropped (database postgres) procs
- pg-lo-get-connection
- pg-get-client-data
- pg-set-client-data!
These were pre-announced in Guile-PG 0.38 (2009-06-22) NEWS.
- Proc `(database postgres) pg-parameter-status' no longer takes keyword
This was pre-announced in Guile-PG 0.38 (2009-06-22) NEWS.
- Maintenance uses autoconf 2.65, automake 1.11, libtool 2.2.6b
- 0.38 | 2009-06-22
- Support for PostgreSQL 7.3 and earlier dropped
Sorry, this was not pre-announced. Note that the subsequent
version, i.e. PostgreSQL 7.4, was released 2003-11-17, over five
years ago.
- Dropped (database postgres) proc: pg-get-connection
This was pre-announced in 0.37 (2008-05-24) NEWS.
- External rep no longer includes "serial number"
- Connection
- Result
These were pre-announced in 0.37 (2008-05-24) NEWS.
- Planned retirement
- pg-lo-get-connection
- pg-get-client-data
- pg-set-client-data!
These (database postgres) procs provide or rely on associations
that can better be expressed using normal Scheme facilities such
as object properties, hash tables, etc, and thus are deemed a
redundant maintenance burden; they WILL BE REMOVED by 2009-12-31.
- Proc `(database postgres) pg-parameter-status' takes symbol `parm'
These are equivalent:
(pg-parameter-status CONN #:session_authorization)
(pg-parameter-status CONN 'session_authorization)
Note, however, that support for keyword `parm' is a misfeature,
and WILL BE REMOVED by 2009-12-31.
- Proc `(database postgres-qcons) sql-quote' more standards compliant
Previously, this did single-quote escaping by inserting a
backslash character prior to every single-quote. The result is
acceptable by PostgreSQL, but is not standards compliant. Now,
it does the escaping by doubling each single-quote, which is
standards compliant and less prone to trigger warnings from the
more recent PostgreSQL versions (8.2 and later).
bef: (sql-quote "a'b") => "'a\\'b'"
now: (sql-quote "a'b") => "'a''b'"
- Changes to `pgtable-manager' (and thus `pgtable-worker')
- Support for DEFAULT
You can now use the keyword #:DEFAULT to specify DEFAULT as the
value to insert into a table, or to update a column. Indeed, for
column values, any keyword now expands to its name (sans `#:').
- #:insert-values no longer filters "serial"
Previously, columns with "serial" type were filtered, so that it
was possible to #:insert-values specifying only values for the
other columns. Now, such usage raises a "column count mismatch"
error; you must explicitly use #:DEFAULT. For example, given a
table with column types "text", "serial", "text":
bef: (W #:insert-values "foo" "bar") => ok
now: (W #:insert-values "foo" "bar") => error
(W #:insert-values "foo" #:DEFAULT "bar") => ok
Although technically speaking the new behavior is incompatible,
the previous behavior was never documented (secret misfeature),
so the impact on your code is likely to be zero (no worries).
- Connection object xrep omits "port" if "host" is a socket dir
When the connection is Unix-domain (i.e., the "host" is a string
that begins with slash that names a directory), the concept of
"port" makes no sense.
- Manual table-of-contents moved forward
It used to be (strangely but perhaps following some outdated
convention) at the end of the document.
- New (database postgres) procs
- pg-mblen
While we wait for Guile to go multibyte (and stay there), this
is a small building-block that eases "mostly ignorant" string
processing.
- pg-server-version
This returns an integer representation of the server version of
a connection, or `#f' if the connection is closed.
- New (database postgres-resx) proc: object<-result
This is useful for `SELECT EXPR;' where the result tuple
consists of one row and one column.
- Maintenance uses autoconf 2.63, automake 1.11, libtool 2.2.6
- 0.37 | 2008-05-24
- Configuration change: search $prefix for PostgreSQL headers/libs
- Change to pg-get-connection
This proc now returns #f if its arg's connection is no longer live.
You should probably avoid it altogether; see following NEWS item.
- Planned modesty
Currently, Guile-PG exposes some accounting (implementation) details
that it shouldn't. These are the "serial number" of connection and
result objects, and the link between a result object the connection
object where it originated. These details WILL BE REMOVED after
2008-10-01; do NOT rely on them. Practically speaking, this means
`pg-get-connection' will be deleted and the external representation
for the objects will drop the "N" field:
until 2008-10-01: #<PG-CONN:N:...> and #<PG-RESULT:N:...>
after 2008-10-01: #<PG-CONN:...> and #<PG-RESULT:...>
- Tests issue SQL commands directly to CREATE and DROP the test database
Previously "make check" required the commands createdb(1) and
dropdb(1) (or destroydb(1) for older PostgreSQL versions) to be
installed on the system. Now, the test infrastructure uses Guile-PG
module (database postgres) to connect to "template1" and issues SQL
commands "CREATE DATABASE" and "DROP DATABASE" directly.
- New (database postgres-meta) proc: information-schema-names
- New (database postgres-meta) proc: information-schema-coldefs
These procs describe Guile-PG's "standard introspection" support,
as specified in the PostgreSQL 7.4.19 documentation (chapter 32,
"The Information Schema").
Additionally, loading the module defines type converters for
`cardinal_number', `character_data' and `sql_identifier'. The
`time_stamp' type converter does not seem to be used and is not
provided.
- New pgtable-manager (and -worker) command: #:finish
This closes the (internal) connection and arranges for all future
invocations of the closure to signal a "dead connection" error.
- Proc `gxrepl' closes connection when done
- New support for #:FOO-all combiners in `parse+make-SELECT-tree'
This (database postgres-qcons) proc now supports #:union-all,
#:intersect-all and #:except-all, as combiners.
- Maintenance uses autoconf 2.62, automake 1.10.1, libtool 2.2.2
- 0.35 | 2008-02-13
- Bugfix: composition INTERSECT in `parse+make-SELECT-tree'
This proc, in module (database postgres-qcons), used to
erroneously accept #:intersection and emit "INTERSECTION".
Now, it accepts #:intersect and emits "INTERSECT".
- New (database postgres) procs
- pg-escape-string-conn
- pg-escape-bytea-conn
- pg-unescape-bytea

(any--OP A B) => ( A OP ANY B )
(all--OP A B) => ( A OP ALL B )
For the latter two, OP is a comparison operator, e.g `='.
Parentheses and commas are added automatically.
- 0.32 | 2007-04-11
- New command for `pgtable-manager': #:tuples-result->rows
This uses `(database postgres-resx) result->object-rows'.
For example:
(define T (pgtable-worker ...))
(define R (T #:select ...))
(equal? (T #:tuples-result->rows R)
(map (lambda (x)
(map cdr x))
(T #:tuples-result->alists R)))
=> #t
- 0.31 | 2007-04-03
- Opaque string support removed
Opaque string support in modules (database postgres-table) and
(database postgres-qcons) has been removed. This was announced
in NEWS below for Guile-PG 0.30 (2006-04-04).
- Support for `pgtable-manager' "data commands" removed
Announced in NEWS below for Guile-PG 0.30 (2006-04-04).
- 0.30 | 2006-04-04
- New stuff for `pgtable-manager' (and by extension `pgtable-worker')
- Support for NULL
You can now use the keyword #:NULL to specify NULL as the value
to insert into a table, or to update a column.
- New command: #:update-col-alist
This is like #:update-col, except that the COLS and DATA are
specified as a single alist arg, not separately.
- New (database postgres) procs
The following procs are associated with the `PQPROTOCOLVERSION'
feature in the `pg-guile-pg-loaded' return value. Note that
this is in contrast to the one-to-one correspondance between
feature and libpq function for previous Guile-PG releases.
- pg-protocol-version
- pg-transaction-status
- pg-parameter-status
- pg-set-error-verbosity
- pg-result-error-field
- pg-ftable
- pg-ftablecol
- pg-fformat
These adhere closely to the C functions in the libpq interface.
Here is a table listing the functions and their behavior for
installations prior to PostgreSQL 7.4.
libpq func behavior: do nothing and return
PQprotocolVersion 2
PQtransactionStatus #:unknown
PQparameterStatus #f
PQsetErrorVerbosity #:default
PQresultErrorField #f
PQftable #f
PQftablecol #f
PQfformat #f
- pg-put-copy-data
- pg-put-copy-end
- pg-get-copy-data
These have a simplified, "more Schemey", interface. They cannot
be used when connected to a "Protocol 2.0" (PostgreSQL 7.3.x and
prior) server.
- pg-exec-params
- pg-exec-prepared
- pg-send-query-params
- pg-send-query-prepared
These have a simplified, "more Schemey", interface, and some
serious (though provisionary) restrictions. They cannot be used
when connected to a "Protocol 2.0" (PostgreSQL 7.3.x and prior)
server. See new section "Parameters" in the manual for details.

Uses guile-1.6 and postgresql-7.4.
Four years of development since the previous version: many changes.
XXX: This package includes a hack since pgsql.bl3.mk does
not provide a way to get the matching -clients package.
Unfortunately, guile{,14}/buildlink3.mk directly includes it, and I don't
know which dependencies actually need libltdl, so it was a recursive bump.
Hopefully this recursive inclusion can be ripped out of
guile{,14}/buildlink3.mk at some point and bubble down to dependencies that
actually use libltdl, avoiding this headache in the future....
in the process. (More information on tech-pkg.)
Bump PKGREVISION and BUILDLINK_DEPENDS of all packages using libtool and
installing .la files.
Bump PKGREVISION (only) of all packages depending directly on the above
via a buildlink3 include.
All library names listed by *.la files no longer need to be listed
in the PLIST, e.g., instead of:
lib/libfoo.a
lib/libfoo.la
lib/libfoo.so
lib/libfoo.so.0
lib/libfoo.so.0.1
one simply needs:
lib/libfoo.la
and bsd.pkg.mk will automatically ensure that the additional library
names are listed in the installed package +CONTENTS file.
Also make LIBTOOLIZE_PLIST default to "yes".
