Thread: pgsql: Doc: Clarify interactions of pg_receivewal with remote_apply
Doc: Clarify interactions of pg_receivewal with remote_apply Using pg_receivewal with synchronous_commit = remote_apply set in the backend is incompatible if pg_receivewal is a synchronous standby as it never applies WAL, so document this problem and solutions to it. Backpatch to 9.6, where remote_apply has been added.
