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. regards, tom lane
