Please, ALWAYS provide Postgresql version & O/S, regardless of whether you
think it is pertinet.

Now try this:

SELECT n.nspname, c.relname as table
FROM pg_class c
JOIN pg_namespace n ON (n.oid =c.relnamespace )
WHERE relkind = 'r' AND
relname NOT LIKE 'pg_%' AND
relname NOT LIKE 'sql_%' AND
relhaspkey = FALSE
ORDER BY n.nspname, c.relname;
