Tom Lane - Defend against bad relfrozenxid/relminmxid/datfrozenxid/datminmxid values
Tom Lane: In commit a61daa14d56867e90dc011bbba52ef771cea6770, we fixed pg_upgrade so that it would install sane relminmxid and datminmxid values, but that does not cure the problem for installations that were already pg_upgraded to 9.3; they'll initially have "1" in those fields. - First-draft release notes for 9.3.5.
Tom Lane: As usual, the release notes for older branches will be made by cutting these down, but put them up for community review first. Note: a few of these items actually don't apply to 9.3, but only to older branches.

Magnus Hagander: pg_ctl will log to the Windows event log when it is running as a service, which is the primary way of running PostgreSQL on Windows. - Allow join removal in some cases involving a left join to a subquery
Tom Lane: We can remove a left join to a relation if the relation's output is provably distinct for the columns involved in the join clause (considering only equijoin clauses) and the relation supplies no variables needed above the join. - pg_basebackup: Add more information about --max-rate option to help output
Peter Eisentraut: It was previously not clear what unit the option argument should have. - Minimal psql tab completion support for SET search_path
Andres Freund: Complete SET search_path = ... - Add autocompletion of locale keywords for CREATE DATABASE
Magnus Hagander: Adds support for autocomplete of LC_COLLATE and LC_CTYPE to the CREATE DATABASE command in psql. - In pg_dump, show server and pg_dump versions with or without --verbose
Tom Lane: We used to print this information only in verbose mode, but it's argued that it's useful enough to print always; one reason being that this provides some documentation about which Postgres versions the dump is meant to reload into. - Remove swpb-based spinlock implementation for ARMv5 and earlier
Robert Haas: Per recent analysis by Andres Freund, this implementation is in fact unsafe, because ARMv5 has weak memory ordering, which means tha the CPU could move loads or stores across the volatile store performed by the default S_UNLOCK.
