In src/backend/catalog/pg_depend.c we find the code for
recordDependencyOn() which is in fact in recordMultipleDependencies(),
and sayth so:
/*
* If the referenced object is pinned by the system, there's no
real
* need to record dependencies on it. This saves lots of space
in
* pg_depend, so it's worth the time taken to check.
*/
So I'm not sure about what we can do here other than error on using
pg_catalog in CREATE EXTENSION? How do we want to manage adminpack?
Other than adminpack, I think it makes sense to say that extensions are
not going into pg_catalog…
