There are tests with injection points in all different test
directories now. I think regress is the only one where it would be too
much of a pain.

I've committed the btree and gist read stream users. I think we can
come back to the test after feature freeze and make sure it is super
solid.

Looking at the spgist read stream user, I see you didn't convert
spgprocesspending(). It seems like you could write a callback that
uses the posting list and streamify this as well.
