postgresql-9.1 9.1.6-1 source package in Ubuntu
Changelog
postgresql-9.1 (9.1.6-1) unstable; urgency=medium * Urgency medium because of data loss bug fix. * New upstream bug fix release: - Fix persistence marking of shared buffers during WAL replay. This mistake can result in buffers not being written out during checkpoints, resulting in data corruption if the server later crashes without ever having written those buffers. Corruption can occur on any server following crash recovery, but it is significantly more likely to occur on standby slave servers since those perform much more WAL replay. There is a low probability of corruption of btree and GIN indexes. There is a much higher probability of corruption of table "visibility maps". Fortunately, visibility maps are non-critical data in 9.1, so the worst consequence of such corruption in 9.1 installations is transient inefficiency of vacuuming. Table data proper cannot be corrupted by this bug. While no index corruption due to this bug is known to have occurred in the field, as a precautionary measure it is recommended that production installations "REINDEX" all btree and GIN indexes at a convenient time after upgrading to 9.1.6. Also, if you intend to do an in-place upgrade to 9.2.X, before doing so it is recommended to perform a "VACUUM" of all tables while having vacuum_freeze_table_age set to zero. This will ensure that any lingering wrong data in the visibility maps is corrected before 9.2.X can depend on it. vacuum_cost_delay can be adjusted to reduce the performance impact of vacuuming, while causing it to take longer to finish. - See HISTORY/changelog.gz for the other bug fixes. * debian/rules: Compress all binaries with xz.
