I see your point, and the comment in pg_dumpall:
# load all the non-postgres users# XXX this breaks badly if the layout of pg_shadow ever changes.# It'd be better to
convertthe data into CREATE USER commands.
 


Well, seems there would be no good way to add columns using pg_dumpall,
even if we waited until 7.1.  The problem is that pg_dumpall assumes
that the databases being dumped and loaded have a pg_shadow with exactly
the same columns, as you noted in your comment.  

Well one solution is to have 7.1 use CREATE USER commands, then add the
pg_shadow columns in 7.2.

If we re-order the new columns to be at the end, those columns will load
in with NULL's.

We could then modify the user code to make default for NULL values in
the new columns.

Another answer is to add some code to COPY to supply default values for
missing  fields when loading pg_shadow.  If we move the new columns to
the end of pg_shadow, that should be only a few lines of C code which we
can remove later.
