Обсуждение: integer datetimes

Has any thought been given to making integer datetimes the default on 
platforms that support it? Are there any performance implications? I saw 
the Tom Lane raised this when it was added, and it looks like the 
decision was deferred. I know that, ceteris paribus, I would rather have 
fixed microsecond precision across a slightly smaller range in every app 
I've ever worked on. Which platforms don't support it? I did some search 
on all these questions but didn't find much info. I'm probably going to 
add the flag enabling it to the default buildfarm setup.

I don't know that anyone's done any serious performance comparisons.
My guess is there wouldn't be a noticeable difference, but that's just
a guess.

The real reason it's not default is portability worries.  We do not
currently have any fundamental functionality that breaks if you don't
have a working int64 datatype, and I'd just as soon not start.

I'm not real thrilled with the idea of a platform-dependent default,
either.

This should be selected for some buildfarm members but not all, just
like other configuration options.

We're very democratic - every member gets to choose their own config ;-)
