I updated the firewall rules on a streaming replication standby server
and thought nothing of it. I later happened to notice on the primary
that ps aux | grep stream didn't show streaming to that server
anymore. On the standby that command still showed the wal receiver
patiently waiting for new data.
I know I broke it, but would anything have eventually happened, or
would the wal receiver keep patiently waiting as the world passed it
by?
I simply restarted the standby cluster and all is well.
Thanks!
