A HUGE number of bug/performance fixes and minor enhancements.
Foreign Keys
Foreign keys are now implemented, with the exception of PARTIAL
MATCH foreign keys. Many users have been asking for this
feature, and we are pleased to offer it.
Optimizer Overhaul
Continuing on work started a year ago, the optimizer has been
overhauled, allowing improved query execution and better
performance with less memory usage.
Updated psql
psql, our interactive terminal monitor, has been updated with a
variety of new features. See the psql manual page for details.
Upcoming Features
In 7.1 or 7.2, we plan to have outer joins, storage for very
long rows, and a write-ahead logging system.
A dump/restore using pg_dump is required for those wishing to migrate
data from any previous release. For those upgrading from 6.5.*, you
can use pg_upgrade to upgrade to this release.
Sqsh (pronounced skwish) is short for SQshelL (pronounced s-q-shell), it
is intended as a replacement for the venerable 'isql' program supplied
by Sybase. It came about due to years of frustration of trying to do
real work with a program that was never meant to perform real work.
Sqsh is much more than a nice prompt, it is intended to provide much of
the functionality provided by a good shell, such as variables,
redirection, pipes, back-grounding, job control, history, command
completion, and dynamic configuration. Also, as a by-product of the
design, it is remarkably easy to extend and add functionality.
FreeTDS is a free (open source, LGPL-licensed) implementation of
Sybase's db-lib, ct-lib, and ODBC libraries. Currently, dblib and ctlib
are most mature. Both of these libraries have several programs know to
compile and run against them. ODBC is just a roughed in skeleton, and
not useful for real work.
FreeTDS will run at protocol versions 4.2, 4.6, or 5.0 and thus can
access both Sybase and Microsoft SQL-Servers. Experimental support for
TDS 7.0 (the version used by MS SQL Server 7.0) is now included.

* binaries which are not JVM dependent go in ${PREFIX}/bin
* jar/zip/etc files for use by java programs go in
${PREFIX}/lib/java
* examples for java packages go in ${PREFIX}/share/examples/java
* documentation for java packages go in ${PREFIX}/share/doc/java
JVMs go in their own directories, right now ${PREFIX}/{java,kaffe}, which
is necessary so that multiple JVMs can be installed concurrently, and so
that the miriad packages which count on ${JAVA_HOME} pointing to a JVM
install will DTRT.
Most java packages already use something similar or can be adapted easily.
Java packages such as Jakarta with large amounts of private java will need
to be addressed separately.
From the change log:
1.7, 5-Jan-00
- NEW: dbcolize now detects and rejects lines that contain embedded
copies of the field separator
- NEW: configure tries harder to prevent people from improperly
configuring/installing jdb
- NEW: tcpdump_to_db converter (incomplete)
- NEW: tabdelim_to_db converter: from spreadsheet tab-delimited files to db
- BUG FIX: dbjoin used to produce incorrect output if there
were extra, unmatched values in the 2nd table.
- BUG FIX: the sample commands in the usage strings
now all should explicitly include the source of data
(typically from "cat foo.jdb |").
- DOCUMENTATION BUG FIX: dbcolmovingstats had incorrect sample output.
1.6, 24-May-99
- NEW: dbsort, dbstats, dbmultistats now run in constant memory
(using tmp files if necessary)
- NEW: dbcolmovingstats does moving means over a series of data
- NEW: dbcol has a -v option to get all columns except those listed
- NEW: dbmultistats does quartitles and medians
- NEW: dbstripextraheaders now also cleans up bogus comments
before the fist header
- BUG FIX: dbcolneaten works better with double-space-separated data
translations.
Depend on tk-postgresql instead of postgresql and fix location of pgtksh
to make this work again (after the restructuring of our postgres package
layout).
unlibtoolized. Things now install into ${PREFIX} instead of
${PREFIX}/${PGSQL_USER} to match hier(7) expectations. The Tcl and Tk
interfaces are now split out into separate packages.
This closes the following PRs: 7384, 8747, 8789, 9272, 9461.
Changes:
- better SQL quoting
Changes for py-mysqldb 0.1.3 that I forgot to note:
- Fixes a coredump at exit under some conditions
- Improved backwards compatability with MySQLmodule.
- Compatibility with MySQL 3.22
- Compliance with Python database API version 2.0
- Thread-safety
- Thread-friendliness (threads will not block each other)
Split PGSQL_USE_TCL into PGSQL_USE_TCL and PGSQL_USE_TK so that postgres
can be built with tcl support on a machine without tk (such as a machine
without X installed...)
