Amit Kapila d9f01a287a Fix a deadlock during ALTER SUBSCRIPTION ... DROP PUBLICATION. ... A deadlock can occur when the DDL command and the apply worker acquire catalog locks in different orders while dropping replication origins. The issue is rare in PG16 and higher branches because, in most cases, the tablesync worker performs the origin drop in those branches, and its locking sequence does not conflict with DDL operations. This patch ensures consistent lock acquisition to prevent such deadlocks. As per buildfarm.
