What makes you think it "keeps running"? It looks to me like the
replication client does that and then goes about its business:

Admittedly, since you seem to have omitted the PID from your
log_line_prefix, it's hard to be 100% sure that these log entries
are from the same process. But I bet they are. The standard
walreceiver definitely does things this way.
In short, I think there's nothing to see here.
