Yes: you must mention a table in FROM to make its field names available
for reference without qualification.  I think we may have tightened that
in recent releases --- the current political climate is to discourage
use of tables without FROM, since SQL92 doesn't allow it at all.

A quick glimpse shows that we still have it in ref/select.sgml (try
'Westward' instead of 'Westwood').  Will fix.
