Are there likely to be enough entries that storage efficiency actually matters? If not, we could use a 2xN array of {key,allowed_value} pairs, that is {{thingy,item1},{thingy,item2},{otherthingy,foo},{otherthingy,bar}} Or perhaps push these out into a separate table, along the lines of oid key allowed_value and use an oidvector to list the selected values in a trigger entry? regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
