I think this breaks contrib/adminpack, and perhaps other extensions.
They'd not be hard to fix with script changes, but they'd be broken.

In general, we would now have a situation where relocatable extensions
could never be installed into pg_catalog.  That might be OK, but at
least it would need to be documented.

Also, I think we'd be pretty much hard-wiring the decision that pg_dump
will never dump objects in pg_catalog, because its method for selecting
the creation schema won't work in that case.  That probably is all right
too, but we need to realize it's a consequence of this.

As far as the code goes, OK except I strongly disapprove of removing
the comment about temp_missing at line 3512.  The coding is not any less
a hack in that respect for having been pushed into a subroutine.  If
you want to rewrite the comment, fine, but failing to point out that
something funny is going on is not a service to readers.
