As has been explained several times already, subtracting one timestamp
from another is going to get an interval not a timestamp:
postgres@production=# select current_timestamp - '01/01/2015'::timestamp;
?column?
--------------------------
194 days 10:37:33.709606
(1 row)
That cannot be turned into a date:
postgres@production=# select to_char(current_timestamp -
'01/01/2015'::timestamp, 'DDD HH:MI:SS.MS');
to_char
------------------
194 10:39:06.994
(1 row)
That is not going to change.
So the question remains:
What are you trying to do, get an interval or get a timestamp?
changed date and changed_dttimezone are are parameters..
select to_char((current_timestamp -
TO_TIMESTAMP(to_char(chaged_date,'YYYY-MM-DD HH24'|| ' '||'MI'||'
'||'SS')||' '||(SELECT utc_offset FROM pg_catalog.pg_timezone_names
WHERE name=changed_dttimezone), 'YYYY-MM-DD HH24'||' '||'MI'||'
'||'SS')::timestamptz),'DDD HH:MI:SS.MS <http://SS.MS>')

But in oracle using systimestamp,to_timestamptz and SS TZH
is not supporting to_timestamp in postgres.
I do not know about Oracle, but in postgres you are
substracting to timestamps ( current_timestamp -
to_timestamp(whatever) ). This gives you an interval.

diffrence is days displaying in postgres query..i thnk
something wrong. is it..?
Days is displaying in postgres query because it is the default
format to display intervals ( it's a little more complicated,
but related ).
$ select '1500 days 8 hours 9 minutes 10 seconds'::interval;
interval
--------------------
1500 days 08:09:10
(1 row)
If you want a particular format you should use the appropiate
formatting functions, like to_char
$ select to_char('1500 days 8 hours 9 minutes 10
seconds'::interval,'DDD HH-MI-SS');
to_char
---------------
1500 08-09-10
(1 row)
Or, you could try to change the default formatting, but this is
generally incorrect.
