Hello hackers, * Description
This patch is a proposal to allow the use of word 'semester' to extract it from date in functions like EXTRACT, DATE_PART, etc and adds the letter 'S' to format the date output in to_char. ** Example SELECT EXTRACT(semester FROM DATE '2015-07-07'); date_part ----------- 2 * Motivation The term is used in a school or college to represent a half-year. Actually it could be evaluated from a date using some math with 'quarter' but could not be extracted from date since the API to define a "reserved word" for EXTRACT is in the core, rather than in SQL. * Syntax I'm using the word 'semester' since it is common in college and school but I wondering if it should be other word (like 'halfyear', for example) Is this a feature that worth? BTW, I'll put this in the commit fest (2015-09). Thanks! -- Dickson S.
