Bug #482: psql (7.1.3) doesn't like sysid=0

Sherwin Daganato (win(at)email(dot)com(dot)ph) reports a bug with a severity of 3
The lower the number the more severe it is.

Short Description
psql (7.1.3) doesn't like sysid=0

Long Description
I have migrated a production database from 7.0.3
to 7.1.3 successfully. Then I was trying to load this
database (7.1.3) to a development machine with
another 7.1.3 when I encounter the error. It is not
clear in the docs that sysid should be positive and
the error message is a little bit confusing.
Why not print "sysid must be greater than zero"?
Why is it that zero sysid is allowed in 7.0.3 and not in
7.1.3?
.

$ psql -f dump.db template1
psql:dumpall_pg:11: ERROR: sysid must be positive

<snip from dump.db>
CREATE USER "root" WITH SYSID 0 CREATEDB CREATEUSER;
</snip from dump.db>
