Just a side note: in addition to its use for partial replication, thismight have potential for performance-prioritizing databases or tablespaces.
hello ...this is an absolutely non-starter. the WAL is designed to be "hyper ordered" and hyper critical. once you fuck up order you will end up with a total disaster. WAL has to be applied in perfect order without skipping depending objects and so on. any concept which tries to get around those fundamental law is either broken.
