Oracle / Postgres Interface

Hi All,

I would appreciate any input on this dilemma:

1. I have DataBase-A which is Oracle on Server A with FunctionA (PLSQL)
2. I have DataBase-B which is Postgress on Server B with FunctionB (PgSQL)
3. I need to call FunctionA from FunctionB

I don’t mind rewriting PgSQL to some other language in Postgress if need be.

Can I do this? If Yes, How?

Please reply as soon as possible.

Thanks,

Sameer
