Comment 4 for bug 588408

I took a look at this as well and it appears that we arrive at the same result sets even if we don't hit the same query plans.

It is my understanding that differences in EXPLAIN plans can be acceptable as the code changes and it might be that we don't need these parts of the test.

The crash is corrected and we produce the same results. However, I'll beat up on the patch with a couple of additional optimizer grammars and post an update on how things went.
