I don't see that in the patch. Your patch changes the syntax LISTEN ColId to mean a regular expression. Even then, having LISTEN "foo" and LISTEN 'foo' mean different things would probably be confusing. I would think about specifying an operator somewhere in the syntax, like you have with LISTEN SIMILAR TO. It would even be nice if a non-built-in operator could be used for matching names. Documentation is missing in the patch. -- Peter Eisentraut http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
