You mean all these apps do is execute a PL/SQL procedure in Oracle? And
they cannot change the syntax in the apps? But they can implement the
logic in PostgreSQL as they do now in Oracle?

Now this is something different IMO. PostgreSQL postmaster does the
listening, but why do the apps need the very same appearance?

How do they connect now? Native Oracle OCI?
