- Table names are in pg_class
- Column names are in pg_attribute, associated to pg_class via "where pg_attribute.attrelid = pg_class.oid"
- Comments are in pg_description... There seem to be links to both pg_class and pg_attribute
- Type info is in pg_type, associated to pg_attribute via "atttypid"
There are attributes that you normally don't see, and "dropped"
attributes still exist in pg_attribute, so things are a tad more
complex than what I have said, but the above 4 tables should provide
you all you need...

Never criticize anybody until you have walked a mile in their shoes,
because by that time you will be a mile away and have their shoes.
