Probably. It just came to my mind because one visitor mentioned he would
look at the bison stuff to do it himself. I meant to enable him to do so
if he likes (and can) without hacking the core product.

That's true, it's the question how much can be offered without too much
effort.
I'm not too deep in oracle stuff, what comes to my mind is
- outer join syntax (parser thing)
- sequences usage (parser too)
- maybe stored procedure call, with a wrapper to convert output
parameters to a composite return value.
There's certainly no point supporting any weird ddl command, so there's
still porting work to be done when migrating.
