First as has been pointed out before Oracle != Postgres.
Also as been pointed out before you have two options:
1) Pay for the EDB Postgres Advanced Sever + and get the Oracle compatibility built ins.
2) Spend the time to convert your Oracle code.
As always it comes down to that magic combination of time and/or money.
Second I do not understand what you are trying to say above. Maybe if you showed some actual code it would help.
