I noticed that gist_page_items() thinks it can hold inter_call_data->rel
open across a series of calls. That's completely unsafe: the executor
might not run the call series to completion (see LIMIT), resulting in
relcache leak complaints. I suspect that it might have cache-flush
hazards even without that. I think this code needs to be rewritten to do
all the interesting work in the first call. Or maybe better, return the
results as a tuplestore so you don't have to do multiple calls at all.
