(approval to update during freeze by agc@)
- 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
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.
Guile-pg is a Guile module providing access and allowing updates to
PostgreSQL databases from Guile scripts. Guile is the GNU interpreter
for the Scheme language and PostgreSQL is a free relational database
management system.
