Not following your argument here. Isn't make_partition_pruneinfo
precisely what is in charge of figuring out whether run-time pruning
is possible?
(See my point in the other thread about Jaime's assertion crash,
that no run-time pruning actually would be possible for that query.
But we got to the assertion failure anyway.)
