Guys, do we need to change this behavior or may be you can tell me that
is normal because this and this:
postgres=# SELECT TO_TIMESTAMP('2016-02-30 15:43:36', 'YYYY-MM-DD
HH24:MI:SS'); to_timestamp
------------------------ 2016-03-01 15:43:36+03
(1 row)
but on the other side we have :
postgres=# select '2016-02-30 15:43:36'::timestamp;
ERROR: date/time field value out of range: "2016-02-30 15:43:36"
LINE 1: select '2016-02-30 15:43:36'::timestamp;
Another bug in to_timestamp/date()?
