Okay, so that's the crux regarding PL/pgSQL.

That would defeat my goal of not rewriting all my Oracle code.

If I were fool enough to plan an attack on the main executor's exception
handling to try and disarm it of its subtransaction semantics, where
would I start?  Where would I end?  What would I do in between?  Can New
Orleans be rebuilt above sea level?

Seriously, though, I'm willing to devote considerable time to this.
Rewriting all my Oracle code function-by-function could be painful, and
I would end up dragging other people around this company into it.  I'm
still trying to hold on to my fantasy that I can hack Postgres (and
contrib/ora2pg) into submission.  In the end I'm hoping that the move
from Oracle will be made easier for others.
