Remove silly completion for "DELETE FROM tabname ...".

tglsfdc · tglsfdc · commit 99ccb2309263 · 2015-12-20T18:29:51.000-05:00
psql offered USING, WHERE, and SET in this context, but SET is not a valid possibility here. Seems to have been a thinko in commit f5ab0a1 which added DELETE's USING option.
