I add MemoryContext listCxt to avoid memory leak. listCxt is created once

I do not sure if the problem was completely solved, so I wait for feedback.
Yeah, I think that solves it.
On further testing, there was actually still a leak with kNN-searches.
Fixed.
I spent a little time cleaning this up. I reverted that pageData change
so that it's an array again, put back the gist_indexonly.sql and
expected output files that were missing from your latest version,
removed a couple of unused local variables that gcc complained about. I
refactored gistFetchTuple a bit, because it was doing IMHO quite bogus
things with NULLs. It was passing NULLs to the opclass' fetch function,
but it didn't pass the isNull flag correctly. I changed it so that the
fetch function is not called at all for NULLs.
I think this is pretty close to being committable. I'll make a round of
editorializing over the docs, and the code comments as well.
The opr_sanity regression test is failing, there's apparently something
wrong with the pg_proc entries of the *canreturn functions. I haven't
looked into that yet; could you fix that?
I have pushed this, after fixing the opr_sanity failure, some bug fixes,
and documentation and comment cleanup.
Thanks for the patch!
