Well, if we wanted to go that far, the simple solution is to rename
tuplesort_gettuple to something else. Guaranteed code breakage then.
However, I think this is overkill for a problem that only *might*
bite people. I kinda doubt that people are using TupleTableSlots in
add-on code, because the design of the executor makes it hard for
anything except plan nodes to obtain slots. You'd have to posit a
piece of code that isn't structured as
while ((tuple = tuplesort_gettuple(...)) != NULL)
{
process tuple;
if (should_free)
pfree(tuple);
}
but instead hangs onto the last tuple past the sort shutdown, and
yet isn't a plan node.
