Previously, the GUC to let the versioned-extension know that the loader was present was incorrectly reset during DISCARD ALL. This caused newly minted parallel workers to throw an error about the extension not being preloaded since it did not know that a loader was, in fact, preloaded. This PR fixes this issue by changing the GUC to a rendezvous variable. It also disables the loader in parallel workers since the loading should have been handled in the parallel leader and the worker start-up logic.
