There was an additional problem I also fixed: TABLE_PURPOSE__FLUSHABLE cannot also define (add) TABLE_PURPOSE__FLUSHABLE_AGGRESSIVE because db_export only wants non-aggressive flushing. But with this definition, all flushing flags returned aggressive.
I removed the addition and ensured that any place that should check both flags is doing so separately.
