This release contains one critical fix over 7.3.6, and some minor items.
A dump/restore is not required for those running 7.3.X.
-
Prevent possible loss of committed transactions during crash
Due to insufficient interlocking between transaction commit and checkpointing, it was possible for transactions committed just before the most recent checkpoint to be lost, in whole or in part, following a database crash and restart. This is a serious bug that has existed since PostgreSQL 7.1.
-
Remove asymmetrical word processing in tsearch (Teodor)
-
Properly schema-qualify function names when pg_dump'ing a CAST
