Hi Marko!
Thanks for the good feedback.
Good point on the pg_listening_channels(). Do you think we could change the
interface of the function? At least PG v10 has changed functions elsewhere
quite dramatically eg. related to xlog functions.
We could change the pg_listening_channels() return type t

LISTEN PATTERN 'foo%' TYPE 'similar'

Hi
This patch adds an ability to use patterns in *LISTEN* commands. Patch uses
