On further review this particular server skipped from 9.2.2 to 9.2.4. This is my most busy and downtime sensitive server and I was waiting on a maintenance window to patch to 9.2.3 when 9.2.4 dropped and bumped up the urgency. However, I have 3 other less busy production servers that were all running 9.2.3 for a while, didnt exhibit the problem, and still dont on 9.2.4.

Thanks very much for the response and investigation, it is much appreciated!

ANALYZE command; all discussion was around autovacuum impact; and
Jan argued that this was leaving things in a status quo for that,
so I conceded the point and left it for a follow-on patch if
someone felt the behavior needed to change. Sorry for the miss.

As far as I'm concerned all effects on the explicit command were
unintended and should be reverted.
