I can supply what Oracle 12.1 does:
SQL> SELECT to_timestamp('2016-06-13 15:43:36', ' YYYY/MM/DD HH24:MI:SS') AS ts
FROM dual;
TS
--------------------------------
2016-06-13 15:43:36.000000000 AD
SQL> SELECT to_timestamp('2016-06-13 15:43:36', 'YYYY/MM/DD HH24:MI:SS') AS ts
FROM dual;
TS
--------------------------------
2016-06-13 15:43:36.000000000 AD
SQL> SELECT to_timestamp('2016-06-13 15:43:36', 'YYYY/MM/DD HH24:MI:SS') AS
ts FROM dual;
TS
--------------------------------
2016-06-13 15:43:36.000000000 AD
(to_timestamp_tz behaves the same way.)
So Oracle seems to make no difference between one or more spaces.

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()?
