I've gone from PostgreSQL to Oracle. If it is just a basic database (no fancy oracle features) then the only things I remember that you should watch for are timestamp data and be aware that in PostgreSQL you can do things that would result in a mutating trigger in Oracle.

This company seems to claim that most of the applications developed in Oracle could be migrated to their database. Any feedback would be appreciated. Thank you Amir
