You will have to rewrite your function in one of the server programming languages on PostgreSQL.

Apart from the usual suspects PL/pgSQL and PL/Perl, you could consider using PL/Java , but you'll have to build it yourself, and don't expect that you can just reuse your Oracle code without modifications.
