Dunno the specific selects to get what you want, but you can investigate the
standard postgres views:
select * from pg_views where viewname like 'pg_%';
Might get you what you're after.
I was doing something similar (creating my own list of tables/ columns)
recently - the various selects are in the source, and quite well documented.
