The ALTER TABLE .. DROP COLUMN support appears in
the PostgreSQL documentation only since version 7.3, see:
	http://www.postgresql.org/docs/7.2/static/sql-altertable.html
	http://www.postgresql.org/docs/7.3/static/sql-altertable.html

The SQL code should already be correct for PG>=73.
( since late december )

Please let me know if pgsql dox are broken/outdated.
