In this case, with the function being called over and over again inside

I think you're going to have to be more specific, because if the
function is stable or immutable, pg will do exactly as you say. Post
the actual query involved.
SELECT distinct(uid) FROM elog,j WHERE elog.type IN(1,4) AND j.id =
elog.jid AND j.pod = 3 AND j.mtotal > 0 AND j.stdate > '2008-01-01
00:00:00.0' AND elog.id >= elog_date_search('2008-01-01 00:00:00') AND
j.stdate < '2008-10-06 23:59:59.0';
