I have been informed that at present (postgres 7.3.2) using IN is not
advised, and I should replace it with EXISTS. I can't seem to get it to
work.
I've tried replacing (example):
SELECT
name
FROM
people
WHERE
state IN (
SELECT
id
You should use something like:
SELECT
name
FROM
people p
WHERE
exists (
SELECT
1
FROM
states
WHERE
name = p.state
)
AND state ~* 'r';

Actually, even better:
select name
from people p, states s
where p.state = s.name
and p.state ~* 'r';
