We can. Here it is. ALL regression tests except for float8
and geometry (only fp differences - diffs checked) passed
'ok'. Checked that createuser and destroyuser work.
This patch changes the catalog pg_user into pg_shadow and
creates a view pg_user that definitely works. Oridinary user
cannot access pg_shadow.
Since your greatest need (to stay with all system stuff named
pg_) is met, you might like it too.
