Well, this is psql and it should be easy; I am not sure pg_catalog.*
fits that requirement. Right now if you do \dt you see user tables, and
\dtS shows system tables; I don't see removing 'S' as being a great
usability gain.
I think searching for both user and system stuff with a pattern is a
no-brainer.
