Answer 1

For your original query, if you take away the group by to look at the pre-grouped result, you'll see why the counts your were receiving were created.

Perhaps the following query utilizing subqueries would achieve your intended result:

SELECT
 t1."id" AS "User ID",
 t1.account_balance AS "Account Balance",
 (SELECT count(*) FROM grocery     t2 ON (t2.user_id=t1."id")) AS "# of grocery visits",
 (SELECT count(*) FROM fishmarket  t3 ON (t3.user_id=t1."id")) AS "# of fishmarket visits"
FROM users t1
ORDER BY t1.id
