…released Pdo\Pgsql::setNoticeCallback() stores a request-allocated fcall cache on the driver handle. A persistent handle outlives the request, so the next request on the same connection uses freed memory as soon as it receives a notice or sets a new callback. Drop the callback from the persistent_shutdown hook, which pdo_sqlite also uses for its user functions, once the last object of the request releases the handle.
