I think what you want here is some way to define a function that takes an arbitrary number of arguments of arbitrary type and let the function figure everything out. I see no reason why this can't be a variant on CREATE FUNCTION, except that of course you need to figure out some API and function resolution details. But it doesn't have to be a completely different concept like a binary plugin. -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
