Make pg_controldata report newest XID with valid commit timestamp

MasaoFujii · MasaoFujii · commit 18d938de7a99 · 2015-09-24T23:31:17.000+09:00
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. Euler Taveira
