Getting in a hurry/distracted.
I wrote out the above test case in psql and with tab completion it is
easy to get to:
delete from delete_test where
and then forget the 'field =' part. Though my more common mistake along
that line is:
delete from delete_test;
At any rate, if it can be done it will be done.
