Please post the EXPLAIN ANALYZE output for the slow query, once
with enable_seqscan on and once with it off. For example:
SET enable_seqscan TO on; -- if not already on
EXPLAIN ANALYZE SELECT * FROM tblassociates WHERE clientnum = 'test';
SET enable_seqscan TO off;
EXPLAIN ANALYZE SELECT * FROM tblassociates WHERE clientnum = 'test';

Please do -- it might help us spot something that could be improved.
What version of PostgreSQL are you using?
