Hello,
the purpose of this patch is to limit impact of pg_backup on running server.
Feedback is appreciated.
Based on a quick look it seems like you're throttling on the receiving
side. Is that a good idea? Especially over longer latency links, TCP
buffering will reduce the effect on the sender side considerably.
Greetings,

Throttling on the sender side requires extending the syntax of
BASE_BACKUP and maybe START_REPLICATION so both can be
throttled but throttling is still initiated by the receiver side.
Maybe throttling the walsender is not a good idea, it can lead
to DoS via disk space shortage.
