Thread: [BUGS] BUG #14527: Calandar Week
The following bug has been logged on the website: Bug reference: 14527 Logged by: John Cantin Email address: jcantin@strategicfuse.com PostgreSQL version: 9.3.6 Operating system: centos 7 Description: Postgres seems to define calendar week differently depending on the function called. The extract function shows '2017-1-1' as week 52 but the to_char function shows it as 1 select extract('week' from '2017-1-1'::date) as week select to_char('2017-1-1'::date,'ww') -- Sent via pgsql-bugs mailing list (pgsql-bugs@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-bugs

Read the manual carefully. (The great thing about standards is there are so many to choose from.) regards, tom lane -- Sent via pgsql-bugs mailing list (pgsql-bugs@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-bugs
