small problem

hi to all

I am doing a webpage and i manipulate data from a postgres database.
I need to do the same thing with a oracle database.
I am using pg_dump to transfer the database data from postgres to oracle
but there are a few problems with same data types in a table when i try to
import it to a oracle database.

create table (...)
(...)
duration interval default 7
hourDay timestamp with time zome
(...)

if i replace this two data types with varchar2(50) it works but i would like
if there's a better choice

thanks for your time and replay
