Good question. The relevant commit is here: commit 6c412f0605afeb809014553ff7ad28cf9ed5526b Author: Tom Lane <[email protected]> Date: Sun May 1 18:56:19 2005 +0000 Change CREATE TYPE to require datatype output and send functions to have only one argument. (Per recent discussion, the option to accept multiple arguments is pretty useless for user-defined types, and would be a likely source of security holes if it was used.) Simplify call sites of output/send functions to not bother passing more than one argument. ...but I don't understand the motivation behind it. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-hackers mailing list ([email protected]) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
