Yeah. I was sort of wondering whether we could get rid of pg_pltemplate
altogether, and instead rely on the extension mechanism to package up
the correct parameters for installing a language. However, one thing
that'd have to be solved before going very far in this direction is the
question of allowing CREATE EXTENSION to non-superusers. We'd at least
need to be able to duplicate the current functionality of allowing
CREATE LANGUAGE to database owners (with an override available to the
DBA).
This seems like a matter for a separate thread though, and not on
pgsql-docs.
