Обсуждение: timestamptz test failed by postgresql 6.5.0
Recently, I compile the Postgresql 9.6.0 on Linux by myself. However, I meet one problem about the timestamptz.sql test case.
The expected timestamptz.out is different from the result of timestamptz.out for ime zone America/Caracas and
America/Santiago
Part of expected timestamptz.out :
DROP TABLE TIMESTAMPTZ_TST;
-- test timestamptz constructors
set TimeZone to 'America/Santiago';
-- numeric timezone
SELECT make_timestamptz(1973, 07, 15, 08, 15, 55.33);
make_timestamptz
---------------------------------
Sun Jul 15 08:15:55.33 1973 CLT
(1 row)
SELECT make_timestamptz(1973, 07, 15, 08, 15, 55.33, '+2');
make_timestamptz
---------------------------------
Sun Jul 15 02:15:55.33 1973 CLT
Part of the result timestamptz.out :
DROP TABLE TIMESTAMPTZ_TST;
-- test timestamptz constructors
set TimeZone to 'America/Santiago';
-- numeric timezone
SELECT make_timestamptz(1973, 07, 15, 08, 15, 55.33);
make_timestamptz
---------------------------------
Sun Jul 15 08:15:55.33 1973 -04
(1 row)
SELECT make_timestamptz(1973, 07, 15, 08, 15, 55.33, '+2');
make_timestamptz
---------------------------------
Sun Jul 15 02:15:55.33 1973 -04
I don't why the timezone in the output "CLT" becomes "-04" in the output. Could anyone please give me some idea to find the trouble cause?
Thanks!
Best Regards!

Hm, did you use configure --with-system-tzdata? If so, this is not
terribly surprising; the 9.6.0 test cases rely on the behavior of the
IANA timezone data as it stood at the time, and those zones changed
since then.
Is there a reason you're trying to build 9.6.0 rather than 9.6.latest,
which includes a fix for this [1] as well as hundreds of
far-more-significant bugs?

Tom, Thanks!
Yes, I compile it by configure --with-system-tzdata, should I remove it?
What's more, because some other components dependency, I must use version 9.6.0.
I also have tried the 9.6.5 version, find the timestamptz test case is updated.
Best Regards!

No. For god's sake, fix whatever components you are using that think
they must have 9.6.0 rather than 9.6.later. Read the release notes [1].
Insisting on 9.6.0 four years later is professional malpractice.
(I'll not even get into the question of whether you should be installing
some later release branch than 9.6.x; but I can't help noting that 9.6's
EOL is 11 months away.)

em~~~, I read the release notes [1] right now.
I try my best fix it as you suggested, and persuade my partners to not use version 9.6.0.
Thanks for your help!
Best Regards!
