PostgreSQL 8.1.16 Documentation | ||||

The release notes contain the significant changes in each PostgreSQL release, with major features and migration issues listed at the top. The release notes do not contain changes that affect only a few users or changes that are internal and therefore not user-visible. For example, the optimizer is improved in almost every release, but the improvements are usually observed by users as simply faster queries.
A complete list of changes for each release can be obtained by viewing the CVS logs for each release. The pgsql-committers email list contains all source code changes as well. There is also a web interface that shows changes to specific files.
The name appearing next to each item represents the major developer for that item. Of course all changes involve community discussion and patch review, so each item is truly a community effort.
Release date: 2009-02-02
This release contains a variety of fixes from 8.1.15. For information about new features in the 8.1 major release, see Section E.17.
A dump/restore is not required for those running 8.1.X. However, if you are upgrading from a version earlier than 8.1.15, see the release notes for 8.1.15.
Fix crash in autovacuum (Alvaro)
The crash occurs only after vacuuming a whole database for anti-transaction-wraparound purposes, which means that it occurs infrequently and is hard to track down.
Improve handling of URLs in headline()
function (Teodor)
Improve handling of overlength headlines in headline()
function (Teodor)
Prevent possible Assert failure or misconversion if an encoding conversion is created with the wrong conversion function for the specified pair of encodings (Tom, Heikki)
Avoid unnecessary locking of small tables in VACUUM (Heikki)
Ensure that the contents of a holdable cursor don't depend on the contents of TOAST tables (Tom)
Previously, large field values in a cursor result might be represented as TOAST pointers, which would fail if the referenced table got dropped before the cursor is read, or if the large value is deleted and then vacuumed away. This cannot happen with an ordinary cursor, but it could with a cursor that is held past its creating transaction.
Fix uninitialized variables in contrib/tsearch2's
get_covers()
function (Teodor)
Fix configure script to properly report failure when unable to obtain linkage information for PL/Perl (Andrew)
Make all documentation reference pgsql-bugs and/or pgsql-hackers as appropriate, instead of the now-decommissioned pgsql-ports and pgsql-patches mailing lists (Tom)
Update time zone data files to tzdata release 2009a (for Kathmandu and historical DST corrections in Switzerland, Cuba)
