Обсуждение: 8.1beta1: pg_dumpall -c does delete from pg_shadow?

Hey all.

Playing around, and pg_dumpall -c does delete from pg_shadow as
part of the role cleanup?

Our friendly psql complains that pg_shadow is a view:
   psql:<filename>:11: ERROR:  cannot delete from a view   HINT:  You need an unconditional ON DELETE DO INSTEAD rule.

And then:
   psql:<filename>:13: ERROR:  role "<role1>" already exists   psql:<filename>:14: ERROR:  role "<role2>" already
exists  psql:<filename>:15: ERROR:  role "<role3>" already exists
 

I assume this is easily reproduceable for others...

Cheers,
mark

Yeah, this is on the open-items list; the DELETE FROM is broken (and
was always a pretty bogus approach anyway), but it's not very clear
what to do instead.
