"no relation entry for relid 1" - Mailing list pgsql-bugs

I've built Postgres from master, and found that the following fairly
simple query breaks:

select count(*)
from
(
    select
    schemaname
    from        pg_stat_user_tables
    order by     1=09
) sub
group by schemaname

This produces the internal error message "no relation entry for relid
1". Why is that?
