Description:

I did some testing on bigint vs double precision datatype performance for a
project we have going on here.

To my surprise, I found the double precision (floating) was well over 200%
faster than bigint in aggregate functions.  I don't know if this qualifies
as a bug, but it sure seems odd considering non-floating type datatypes
usually perform much faster than floating.

Please contact me if you wish to discuss.
