Hi
2017-10-11 12:35 GMT+02:00 <kes-...@yandex.ru>:
The following bug has been logged on the website:
Bug reference: 14850
Logged by: Eugen Konkov
Email address: kes-...@yandex.ru
PostgreSQL version: 10.0
Operating system: Linux mint 18: Linux work 4.4.0-57-generic #78-Ubu
Description:
Hi. I try to do next math:
select extract( month from justify_days( timestamp '2016-01-31' +interval '1
month' -timestamp '2016-01-31') );
date_part
-----------
0
(1 row)
I expect `1` but get `0`. But here everything is right:
>Adjust interval so 30-day time periods are represented as months
https://www.postgresql.org/docs/9.6/static/functions- datetime.html
But with ability to setup justify date the math will be more sharp.
Please implement next feature:
select extract( month from justify_days( timestamp '2016-01-31' +interval '1
month' -timestamp '2016-01-31'), timestamp '2016-01-31' );
date_part
-----------
1
(1 row)
This is useful when I try to calculate how much month are left between
service start and end dates.
This is not the bug, so pgsql-hackers, pgsql-general are better places for this discussion
I am thinking so your request has sense, and should be registered in ToDo list https://wiki.postgresql.org/wiki/Todo
You can try to connect people from PostgreSQL Pro company for implementation.
Regards
Pavel
Thank you.
