I'm thinking that you're asking from something along
these lines:
SELECT count(*)
FROM gob
WHERE gid IN
(SELECT gid FROM comb2
WHERE seq_id IS NOT NULL);
This will give you a count of gid instances in table
'gob' that are also in the table 'comb2' with at least
one seq_id assigned.
Sub-selects - gotta love 'em.
Hope this helps.
