Maxim Gekk updated SPARK-29370:
-------------------------------
Description:
In PostgreSQL, Quantities of days, hours, minutes, and seconds can be specified
without explicit unit markings. For example, '1 12:59:10' is read the same as
'1 day 12 hours 59 min 10 sec'. For example:
{code:java}
maxim=# select interval '1 12:59:10';
interval
----------------
1 day 12:59:10
(1 row)
{code}
It should allow to specify the sign:
{code}
maxim=# SELECT interval '1 +2:03:04' minute to second;
interval
----------------
1 day 02:03:04
maxim=# SELECT interval '1 -2:03:04' minute to second;
interval
-----------------
1 day -02:03:04
{code}
