Fair point, but doesn't it apply equally to non-default ACLs on any
other system objects? If you tweaked the permissions on say pg_ls_dir(),
then dump, then tweak them some more, you're going to get uncertain
results if you load that dump back into this database ... with or without
--clean, because we certainly aren't going to drop pinned objects.
I think we could jigger things so that we dump the definition of these
special quasi-system objects only if their ACLs are not default, but
it's not clear to me that that's really an improvement in the long run.
Seems like it's just making them even wartier.
