Or just use the information_schema like this:
select table_schema, table_name from information_schema.tables;
It's also possible to get mostly the same info using pg_class catalog:
select relname from pg_class where relkind = 'r';
but that may require a bit more work, if you want schema names too for
example (as the query executed by psql illustrates).
