We do consume extra space from input string, but not if it is in format string, see below:

postgres=# SELECT TO_TIMESTAMP('2016-06-13      15:43:36', 'YYYY/MM/DD HH24:MI:SS'); 
to_timestamp 
------------------------
2016-06-13 15:43:36-07
(1 row)

We should have same treatment for format string too.

Thoughts? Comments?
