Zoltan, could you please explain why you unrolled FORWARD and BACKWARD? I tried
applying the rest of your patch, without this unrolling but didn't get any
shift/reduce problem. Might have been that I missed something, so could you please try again?

Tom, AFAICT we only need one core grammar change, moving the cursor name to
it's own rule that only resolves back to name. This rule should be eliminated
by bison during the build process anyway, so I see no problem adding it. It
does make the ecpg changes way smaller though. Is this okay with you?

Zoltan, two more things about this patch need to be cleared:
- I don't think your code is able to handle varchars.
- There is no test. Please add this to some of our test cases or write a new one.

Some variable handling commands look suspicious to me, a test case might
alleviate my concerns.
