A quick "grep" shows that there is nothing named "day_inc" in core
Postgres nor any of the contrib extensions. So this is something
homegrown. It looks to me like somebody wanted a plus operator
that would add numerics and dates/timestamps/timestamptzs, and
figured they could be lazy and make one operator using "anyelement".
But this will capture numeric plus *anything*, so it was not a
good idea. I'd recommend dropping the use of anyelement and just
making three non-polymorphic operators.
