We can split pg_proc into pg_procinfo and pg_procsrc.
pg_procinfo contains all information about function except source code and
is readable to all.
pg_procsrc has the source and readable only to system and superusers.
pg_proc is a view that joins the two. If database developer wants to limit
user access, they add conditions to the view as necessary, e.g.
proowner in ('postgres',current_user)
or whatever they want.
