I agree that "semester" was not nice, the real meaning is "half" or
"halfyear" as mentioned in other messages. That's it, I was proposing
the extraction of the first or second half year using a specific word
like in:
select extract('halfyear' from date '2015-08-15')); or select date_trunc('halfyear', date '2015-08-15');
rather than trying to overloading `date_part` with a UDF or
calculating half like:
select ceil(date_part('quarter', date '2015-08-15') / 2);
BTW, I feel that I have enough feedback to set patch as rejected.
Thank you for your time.
