It looks to me that you have introduced a buffer leak into
heap_get_latest_tid ... which is quite unlikely to be worth optimizing
anyway. EvalPlanQual is not exactly a performance-critical path either,
and given how hard that code is to understand at all, complicating it
for marginal performance gains seems dubious.
