* 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 indexes. 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.
