Re: "HDT" time zone not recognized by PostreSQL 9.5

Neither are the more modern HADT and HAST time zones recognized by PostreSQ=
L 9.5

So, the only Hawaiian timezone recognized by PostreSQL 9.5 is HST, thus the=
 following would run fine:
SELECT TIMESTAMP '2013-08-13 00:00:00' AT TIME ZONE 'HST';

While all these would fail:

SELECT TIMESTAMP '2013-08-13 00:00:00' AT TIME ZONE 'HDT';

SELECT TIMESTAMP '2013-08-13 00:00:00' AT TIME ZONE 'HADT';

SELECT TIMESTAMP '2013-08-13 00:00:00' AT TIME ZONE 'HAST';
