But there is the possibility of replication conflicts, which can either delay replay of the WAL or lead to cacneled queries on the standby. To see why this is unavoidable in some cases, consider the following scenario: - on the standby, there is a long-running query on table A - on the primary, somebody executes "DROP TABLE A" The change gets replicated to the standby, but it clearly cannot be replayed while the query is still running.
