An approach such as ora2pg solves a specific problem. It doesn't
really solve the general problem of people familiar with Oracle who
want to use Postgres. It doesn't at all solve my problem, which is to
have an application which can easily speak to either Oracle or
Postgres.

That's why I'm implementing a different parsing algorithm.
