I understand the temptation to forbid pg_catalog as the target schema
for relocatable extensions, or indeed for object creation in general.
The fact that you can't, for example, go back and drop the objects
later is a real downer. On the other hand, from a user perspective,
it's really tempting to want to create certain extensions (adminpack,
for example) in such a way that they appear to be "part of the system"
rather than something that lives in a user schema. Had we some other
solution to that problem (a second schema that behaves like pg_catalog
but is empty by default and allows drops?) we might alleviate the need
to put stuff in pg_catalog per se.
