No, we should by secure by default. You usually want to lock down
tightly where replication connections can come from. You know the IP
addresses of your standby servers, so it shouldn't be hard to
If "all" includes replication connections, that makes it harder to
configure pg_hba.conf correctly so that you allow normal connections
from anywhere, but only allow replication connections from a specific IP
address. You'd need two lines, first one to accept replication
connections from the standby, and a second one to reject them from
anywhere else.
But I wonder if we should add lines in the default pg_hba.conf to
"trust" replication connections from loopback, like we do for normal
connections?
