I'm a unhappy how this is reusing SIGINT for WalSndLastCycleHandler. Normally INT is used cancel interrupts, and since walsender is now also working as a normal backend, this overlap is bad. Even for plain walsender backend this seems bad, because now non-superusers replication users will terminate replication connections when they do pg_cancel_backend(). For replication=dbname users it's especially bad because there can be completely legitimate uses of pg_cancel_backend(). - Andres -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
