You can store them comma-separated in a single column, or as
multiple rows, from which you extract a column. The Postfix
(My|Pg)SQL driver will then automatically join the results with
a ",".
If you want predictable ordering, you may need to also have a
priority column, the PgSQL syntax would be:
SELECT r
FROM ( SELECT restriction, priority
FROM restrictions
WHERE email = '%s'
ORDER BY priority
) AS T(r, p);
