commit 4f714b2fd2a580d909607de889ac822956eb8299
Author: Robert Haas <rhaas@postgresql.org>
Date: Thu Oct 27 18:27:40 2016 +0000
If the stats collector dies during Hot Standby, restart it.
This bug exists as far back as 9.0, when Hot Standby was introduced,
so back-patch to all supported branches.
Report and patch by Takayuki Tsunakawa, reviewed by Michael Paquier
and Kuntal Ghosh.
