From 2d8a8b18fe5a88146cb8baff591137fa724d86da Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Tue, 28 Sep 2021 17:34:31 -0400 Subject: [PATCH] Fix instability in contrib/bloom TAP tests. It turns out that the instability complained of in commit d3c09b9b1 has an embarrassingly simple explanation. The test script waits for the standby to flush incoming WAL to disk, but it should wait for the WAL to be replayed, since we are testing for the effects of that to be visible. While at it, use wait_for_catchup instead of reinventing that logic, and adjust $Test::Builder::Level to improve future error reports. Back-patch to v12 where the necessary infrastructure came in (cf. aforesaid commit). Also back-patch 7d1aa6bf1 so that the test will actually get run.
