From: Tom Lane Date: Tue, 16 Oct 2018 16:01:18 +0000 (-0400) Subject: Improve stability of recently-added regression test case. X-Git-Tag: REL_12_BETA1~1386 X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=17d6a8fb764c95536c08742a7f94705e9774db05;p=postgresql Improve stability of recently-added regression test case. Commit b5febc1d1 added a contrib/btree_gist test case that has been observed to fail in the buildfarm as a result of background auto-analyze updating stats and changing the selected plan. Forestall that by forcibly analyzing in foreground, instead. The new plan choice is just as good for our purposes, since we really only care that an index-only plan does not get selected. Back-patch to 9.5, like the previous patch.
