Обсуждение: timestamp refactor effort

So...in the vein of my last mail, I have tried to create another patch
for refactoring out some of the HAVE_INT64_TIMESTAMP ifdefs in the
code in timestamp.c. I have attached the patch. Please let me know if
this patch is acceptable and what I can do to continue this effort.

Thanks,
wt

Hmm, PackedTime seems like a fairly random name for the type --- there's
not anything particularly "packed" about it IMO.

I'm a bit inclined to suggest just using the Timestamp typedef.
I guess though that there's some risk of confusion between values
that actually are "timestamp without time zone" and values that need
the same representation but aren't actually intended to represent a
specific point in time.

Maybe "TimeOffset" or "TimeValue" or something like that?

Other than the name game, I think you're headed in the right direction.

I do agree that Timestamp seems to express the same thing PackedTime
does Should we rename Timestamp to TimeOffset?

Thanks.

I have a question. Are the low level representations of Timestamp and
TimestampTZ the same?

They're the same but the interpretations are different, which is why
I think it's useful to have two typedefs as a way of documenting what
any given value is intended to be.  The argument for having a third
typedef would be exactly the same: to help document what a value is
intended to be.

Makes sense.
