Logical replication carries rows but not DDL, so a migration that adds a
column stalls every subscriber with "missing replicated columns" until the
column exists there too. _prisma_migrations is replicated, so migrate deploy
on a subscriber reports nothing pending while its tables lag behind.
sync-replica-schema.sh applies pending migrations to each subscriber first,
tracking them locally in _replica_ddl_applied, then migrates the publisher.
--check reports subscription state and columns missing on any replica.
