Subject: pgsql: Add a test harness for the LWLock tranche code.
Date: Thu, 18 Sep 2025 20:23:59 +0000
Message-ID: <E1uzLAd-001Nxh-1P@gemulon.postgresql.org> (raw)

Add a test harness for the LWLock tranche code.

This code is heavily used and already has decent test coverage, but
it lacks a dedicated test suite.  This commit changes that.
