Yes, there is. If there is a query in progress, pg_get_result() will block and return the result of that query when it's complete.

There is no way to poll/wait for a notification to come in. You either have to enter a busy loop or sleep. Both options are horrible. It would be nice for PHP to provide access to PQsocket so one could select() on the socket connection. This is how it's done from C or Perl.
