Re: BUG #2477: Aggregate Integer divisors incorrectly yield integer-type quotient

What's your point?  Postgres has always defined division of integers as
yielding an integer result.  AFAICS this choice is fully sanctioned by
the SQL standard:

         1) If the data type of both operands of a dyadic arithmetic opera-
            tor is exact numeric, then the data type of the result is exact
            numeric, with precision and scale determined as follows:
            ...
            d) The precision and scale of the result of division is
              implementation-defined.

(SQL92 6.12 <numeric value expression> syntax rule 1)

Sayonara.  Last I checked, they had a few idiosyncrasies too.
