From 3f5863e15664757393c7a1416181fb58deac37a6 Mon Sep 17 00:00:00 2001 From: Bruce Momjian Date: Mon, 15 Jun 2020 20:59:40 -0400 Subject: [PATCH] pg_upgrade: set vacuum_defer_cleanup_age to zero Non-zero vacuum_defer_cleanup_age values cause pg_upgrade freezing of the system catalogs to be incomplete, or do nothing. This will cause the upgrade to fail in confusing ways.
