Another way to do it is to have one entry, put the full set of arguments
into the initial pg_proc.dat data, and then use CREATE OR REPLACE FUNCTION
later during initdb to install some defaults. See existing cases in
system_views.sql, starting about line 1180. Neither way is especially
pretty, so take your choice.
