interpret a column name as an output column alias (targetlist AS name),
ather than a real column name as it ought to. According to the spec,
only ORDER BY should look at output column names. I left in GROUP BY's
willingness to use an output column number ('GROUP BY 2'), even though
this is also contrary to the spec --- again, only ORDER BY is supposed
to accept that. But there is no possible reason to want to GROUP BY
an integer constant, so keeping this old behavior won't break any
SQL-compliant queries. DISTINCT ON will behave the same as GROUP BY.
Change numerology regress test, which depended on the incorrect
behavior.
