Fix persistence marking of shared buffers during WAL replay (Jeff Davis)

\n

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\", which might lead to wrong answers from index-only scans. Table data proper cannot be corrupted by this bug.

\n

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 9.2.1.

\n

Also, it is recommended to perform a VACUUM of all tables while having vacuum_freeze_table_age set to zero. This will fix any incorrect visibility map data. vacuum_cost_delay can be adjusted to reduce the performance impact of vacuuming, while causing it to take longer to finish.
