I thought for sure this was on the FAQ...
What you are looking for is the behavior of psql's \dt command.
You can look at the psql source to get the exact query, but it's
something like this:
SELECT * FROM pg_class
The \dt command filters out the system (WHERE rel_name NOT LIKE 'pg_%')
tables and some other things so I'd look at it otherwise you get a few
hundred tables in an empty database.
