See the SELECT documentation:

http://www.postgresql.org/docs/8.0/static/sql-select.html

"When an alias is provided, it completely hides the actual name of
the table or function; for example given FROM foo AS f, the remainder
of the SELECT must refer to this FROM item as f not foo."

If you disable add_missing_from then you'll get an error instead
of a notice and unexpected results. Add_missing_from will be
disabled by default in PostgreSQL 8.1.
