Subject: pgsql: Test that VM clear registers VM buffers
Date: Wed, 15 Jul 2026 21:32:49 +0000
Message-ID: <E1wk7Dk-000M0c-0V@gemulon.postgresql.org> (raw)
Test that VM clear registers VM buffers
The WAL summarizer only tracks registered buffers, so unregistered VM
clears are ommitted from incremental backups, corrupting the restored
visibility map. Test those cases are now fixed.
