Most important change was serious bug in 3.5 that did not allow DB-API 2.0
version to work without a manual change.
Other changes:
- Better DB-API 2.0 compliance
- Exception hierarchy moved into C module and made available to both APIs
- Fix error in update method that caused false exceptions
- Moved to standard exception hierarchy in classic API
- Added new method to get transaction state
- Use proper Python constants where appropriate
- Use Python versions of strtol, etc. Allows WIN32 build
- Bug fixes and cleanups
this package build standalone. py-postgresql uses it's own version
numbering and really doesn't have much to do with the rest of the
postgresql packages.
extension Makefile fragments, because they really don't have anything to
do with the buildlink[12] frameworks. Change all the Makefiles that use
application.buildlink.mk and extension.buildlink.mk to use application.mk
and extension.mk instead.
<explorer@flame.org> for most of the work on this update.
Pkgsrc changes from the previous version include removing Makefile.ssl and
some patches that have been integrated into this release of PostgreSQL. We
leave open the question of when to byte-compile the Python modules for the
PyGreSQL interface and just do it as before, although we should consider
doing the compilation as a post-install step to ensure that the timestamps
are correct. We also reorder some lines in the Makefile to include
Makefile.common below certain definitions (GNU_CONFIGURE, USE_BUILDLINK_ONLY)
as they may possibly trigger different portions of Makefile.common.
*** Please note that a dump/restore is required to migrate an existing ***
*** PostgreSQL installation to 7.2. ***
Major changes from version 7.1.3 are geared toward improving use in
high-volume applications and include:
VACUUM
Vacuuming no longer locks tables, thus allowing normal user access
during the vacuum. A new "VACUUM FULL" command does old-style
vacuum by locking the table and shrinking the on-disk copy of the
table.
Transactions
There is no longer a problem with installations that exceed four
billion transactions.
OID's
OID's are now optional. Users can now create tables without OID's
for cases where OID usage is excessive.
Optimizer
The system now computes histogram column statistics during
"ANALYZE", allowing much better optimizer choices.
Security
A new MD5 encryption option allows more secure storage and
transfer of passwords. A new Unix-domain socket authentication
option is available on Linux and BSD systems. PAM authentication
is also available.
Statistics
Administrators can use the new table access statistics module to
get fine-grained information about table and index usage.
FOO_REQD=1.0 being converted to foo>=1.0, one can now directly specify
the dependency pattern as FOO_DEPENDS=foo>=1.0. This allows things like
JPEG_DEPENDS=jpeg-6b, or fancier expressions like for postgresql-lib.
Change existing FOO_REQD definitions in Makefiles to FOO_DEPENDS.
adds a few minor features and makes a few speedups in the code, plus:
- Fix some DB-API quoting problems (niall.smart@ebeon.com)
- Moved development into PostgreSQL development tree.
This release fixes a few bugs, adds a few minor features and makes a
few speedups in the code.
Important changes from PyGreSQL 3.0 to PyGreSQL 3.1
- Fix some quoting functions. In particular handle NULLs better.
- Use a method to add primary key information rather than direct
manipulation of the class structures.
- Break decimal out in _quote (in pg.py) and treat it as float.
- Treat timestamp like date for quoting purposes.
- Remove a redundant SELECT from the get method speeding it, and insert
since it calls get, up a little.
- Add test for BOOL type in typecast method to pgdbTypeCache class.

- Fix pgdb.py to send port as integer to lower level function
(dildog@l0pht.com)
- Change pg.py to speed up some operations
- Allow updates on tables with no primary keys.
the Python DB-API module. Also, note backwards compatibility issue.
Important changes for 3.0
Remove strlen() call from pglarge_write() and get size from object.

Add a little more error checking to the quote function in the wrapper
Add extra checking in _quote function
Wrap query in pg.py for debugging

Add DB-API 2.0 wrapper pgdb.py (andre@via.ecp.fr)
Correct keyword clash (temp) in tutorial
Clean up layout of tutorial
Return NULL values as None (rlawrence@lastfoot.com) (WARNING: This will
cause backwards compatibility issues.)
Change None to NULL in insert and update
Change hash-bang lines to use /usr/bin/env
Clearing date should be blank (NULL) not TODAY

Many fixes by chifungfan@yahoo.com, tony@printra.net, jeremy@alum.mit.edu
and others to get the final version ready to release.
