Now I was wondering if a DELETE statement could be rewritten with the same
"strategy":
Not at the moment. There have been discussions of allowing the same
table name to be respecified in USING, but there are complications.
However it works.
DELETE FROM some_table USING some_table AS s
WHERE
some_table.col1 = s.col1 AND
some_table.col2 = s.col2 AND
some_table.id < s.id;
But that's not an outer join
