Subject: pgsql: Don't enter parallel mode when holding interrupts.
Date: Wed, 18 Sep 2024 02:58:48 +0000
Message-ID: <E1sqku0-001aT7-5u@gemulon.postgresql.org> (raw)

Don't enter parallel mode when holding interrupts.

Doing so caused the leader to hang in wait_event=ParallelFinish, which
required an immediate shutdown to resolve.  Back-patch to v12 (all
supported versions).
