List all tables in postgresql information_schema

You should be able to just run select * from information_schema.tables to get a listing of every table being managed by Postgres for a particular database.

You can also add a where table_schema = 'information_schema' to see just the tables in the information schema.

For listing your tables use:

SELECT table_name FROM information_schema.tables WHERE table_schema='public'

It will only list tables that you create.

\dt information_schema.

from within psql, should be fine.
