Subject: Make pg_controldata report newest XID with valid commit timestamp
X-Git-Url: http://git.postgresql.org/gitweb/?a=commitdiff_plain;h=18d938de7a99d698d33cc3a94507c8fe0a0005ab;p=users%2Frhaas%2Fpostgres.git

Make pg_controldata report newest XID with valid commit timestamp

Previously pg_controldata didn't report newestCommitTs and this was
an oversight in commit 73c986a.

Also this patch changes pg_resetxlog so that it uses the same sentences
as pg_controldata does, regarding oldestCommitTs and newestCommitTs,
for the sake of consistency.

Back-patch to 9.5 where track_commit_timestamp was added.
