You can do that today, as long as you don't mind schema-qualifying
uses of the function:
regression=# create function pg_temp.tfunc(int) returns int as
regression-# $$ select $1 + 1 $$ language sql;
CREATE FUNCTION
regression=# select pg_temp.tfunc(42);
tfunc
-------
43
(1 row)
Without the qualification, the function won't be found, even if
you put pg_temp into your search path explicitly. That's intentional
because of the risk of trojan horses ...
