The pg_notify() function wraps the given channel name in quotes if needed. Most people find it easiest to keep all identifiers lower case to avoid such issues. -Kevin -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
