The issues you list are not with predefined roles at all, but with the
changes to dump ACLs defined against objects in pg_catalog. I've also
got patches to address those issues already developed and (mostly)
posted. I'll be posting a new set later today which addresses all of
the known issues with dumping catalog ACLs.
There is an ongoing thread where Noah and I have been discussing the
dumping of catalog ACLs issues and the TAP test suite which I've been
developing for pg_dump. Certainly, anyone is welcome to join in that
discussion.
As mentioned before, the concern raised about predefined roles are the
checks which were added to make them unlike regular roles. I'll be
posting a patch tomorrow to revert those checks, as I mentioned on
another thread earlier today.
Thanks!
Stephen
