Connection limit doesn't work for superuser
Hi hackers!
It would be nice if ALTER USER ... WITH CONNECTION LIMIT will work for superuser. It would protect against connection
leaks.e.g. we have two superusers, one of them reached connection limit but not max_connections, the other is still
possibleto connect to database and solve the problem. The current behaviour would be the same for the case with
rolconnlimit= -1. Superuser can execute NOLOGIN to another superuser and it works. I found previos discussion about
CONNECTIONLIMIT for superuser but it ended about Slony.
