It's not a bug.

You still haven't responded to my query: did you try it in the same
database that pg_dumpall is connecting to? My guess is that you have
munged the permissions on pg_shadow or pg_authid without understanding
that that will only take effect in the one database you do it in.
pg_dumpall is connecting to either "postgres" or "template1" depending
on version; what's the permissions situation in that database?
