From 5940d1b027d750103daf99af48a4cd93be12e148 Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Wed, 19 Jan 2022 16:29:09 -0500 Subject: [PATCH] TAP tests: check for postmaster.pid anyway when "pg_ctl start" fails. "pg_ctl start" might start a new postmaster and then return failure anyway, for example if PGCTLTIMEOUT is exceeded. If there is a postmaster there, it's still incumbent on us to shut it down at script end, so check for the PID file even though we are about to fail. This has been broken all along, so back-patch to all supported branches.
