commit b15ab18ed7e30d2e404f385c3b59d7b3768b141b
Author: Tom Lane <tgl@sss.pgh.pa.us>
Date: Fri May 13 00:04:12 2016 +0000
First released in: 9.6.0, 9.1.23, 9.2.18, 9.3.14, 9.4.9, 9.5.4
Ensure plan stability in contrib/btree_gist regression test.
Buildfarm member skink failed with symptoms suggesting that an
auto-analyze had happened and changed the plan displayed for a
test query. Although this is evidently of low probability,
regression tests that sometimes fail are no fun, so add commands
to force a bitmap scan to be chosen.
