One thing I would like to see is features like this added to the opclasses (or opfamilies?) using standard PG functions that return standard PG data types. So if each opclass had a function that took the data type in question and returned a bytea then you could implement that function using a language you felt like (in theory), test it using standard SQL, and possibly even find other uses for it. That kind of abstraction would be more promising for the future than having yet another C api that is used for precisely one purpose and whose definition is "provide the data needed for this usage". -- greg -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
