select * from applicants as a where (a.created::date > '05-01-2000' or

There is one of the queries.. I just remembered that the order by was added
since last time I checked it's PLAN (in the 6.5.X days) -- could that be the
problem?
8784 records in the applicant database.
created and resubmitted are both timestamps.
