As failures to use a generic plan goes, that one's fairly tame. I've seen much worse. For example:
PREPARE foo(integer[]) AS SELECT * FROM complexview WHERE id = ANY ($1); where the caller typically supplies 1-5 array elements (or any number less than 10, because generic parameter arrays are assumed to have 10 elements). This one can be a massive performance regression between 9.1 and 9.2; the first guy who mentioned this on IRC was getting a 40x slowdown (~20ms planning time vs. 0.5ms execution time). -- Andrew (irc:RhodiumToad) -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
