The following bug has been logged on the website:
Bug reference: 12675
Logged by: Derek Anderson
Email address: derek(dot)anderson(at)mspmac(dot)org
PostgreSQL version: 9.4.0
Operating system: Linux
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.
