People have been saying that on this list forever, and I agree you
shouldn't *depend* on column order, but why does INSERT syntax allow
you to omit the column names?
INSERT INTO sometable VALUES (1, 2, 3);
If columns inherently don't have an ordering, this shouldn't be
possible because it would make no sense.
Things like this INSERT syntax and the fact that columns are always
returned in the same order when you "SELECT *" or when you check the
table definition with \d condition people to expect being able to
influence the order of columns.
