Tom,
You need to
look into what the estimated vs actual rowcounts are for just the
two-column condition (ie, where nid = something AND iid1 = something).
Getting those estimates to match reality is the key to getting a sane
plan choice here.
Many thanks - I agree in principle it isn't

Hi Tom,
- increasing the statistics target to the maximum setting with SET
STATISTICS 1000 on columns rid, nid and iid1 of answers, then
re-vacuuming.
I hope you meant re-analyzing.
Hehe absolutely yes; I always VACUUM VERBOSE ANALYSE :)

Tom,
Index Scan using index_answers_nidiid1 on answers
(cost=0.00..114.14 rows=1 width=60) (actual time=0.206..2398.645
rows=21891 loops=1)

Well, here's the problem all right: 1 row estimated vs 21891

There isn't another way to download 8.4devel that isn't

I mean, i need source code, but in my work i can't

I should say I'd pad them to match length with the input value.

Hi, Dimitris
I think simple
SELECT TABLENAME.id
FROM TABLENAME
WHERE prm_patern ilike TABLENAME.candidate_pattern||'%'
ORDER BY |char_length(|TABLENAME.candidate_pattern) desc
LIMIT 1
should do the trick. (Provided TABLENAME is not very large of course)

The function runs just fine till this select statement

This goes to the work order header table
