PostgreSQL 7.3 on Cygwin rejects all-numeric userid, pg_class_aclcheck

When I changed from 7.2.3 to 7.3 I noticed this behavior.

I did a clean install of the most recent cygwin and PostgreSQL on WinXP
Pro under user '249779', which is a member of Administrators. With
7.2.3, all was fine. With 7.3 (also a clean install), initdb worked fine
but creating a database with createdb or trying to connect (to
template1) with psql failed. I believe it was psql that complained [from
aclchk.c, I think]:

            pg_class_aclcheck: invalid user id 249779

After changing my userid to 'harbison' and reinstalling cygwin and 7.3
in the same fashion, there were no errors.
