Not necessarily --- that's an optional feature.  In fact, I am not eager
to encourage third-party PLs to start installing pg_pltemplate entries
anymore, because that's mostly vestigial in the extensions universe.
We should be encouraging use of CREATE EXTENSION not CREATE LANGUAGE to
install PLs, and for that you don't need a pltemplate entry.  It's
likely that pg_pltemplate will disappear entirely before long.
