postgresql-8.4 (8.4.15-0ubuntu12.04) precise-proposed; urgency=low
* New upstream bug fix release: (LP: #1088393)
- Fix multiple bugs associated with "CREATE INDEX CONCURRENTLY"
Fix "CREATE INDEX CONCURRENTLY" to use in-place updates when
changing the state of an index's pg_index row. This prevents race
conditions that could cause concurrent sessions to miss updating
the target index, thus resulting in corrupt concurrently-created
Also, fix various other operations to ensure that they ignore
invalid indexes resulting from a failed "CREATE INDEX CONCURRENTLY"
command. The most important of these is "VACUUM", because an
auto-vacuum could easily be launched on the table before corrective
action can be taken to fix or remove the invalid index.
- See HISTORY/changelog.gz for details about other bug fixes.
