The following documentation comment has been logged on the website:
Page: https://www.postgresql.org/docs/15/runtime-config-replication.html
Description:
hello ,everyone,
in the url
https://www.postgresql.org/docs/15/runtime-config-replication.html, there
are following description:
max_wal_senders (integer)
Specifies the maximum number of concurrent connections from standby servers
or streaming base backup clients (i.e., the maximum number of simultaneously
running WAL sender processes). The default is 10. The value 0 means
replication is disabled. Abrupt disconnection of a streaming client might
leave an orphaned connection slot behind until a timeout is reached, so this
parameter should be set slightly higher than the maximum number of expected
clients so disconnected clients can immediately reconnect. This parameter
can only be set at server start. Also, wal_level must be set to replica or
higher to allow connections from standby servers.
When running a standby server, you must set this parameter to the same or
higher value than on the primary server. Otherwise, queries will not be
allowed in the standby server.
In the above description， there is no description about "Logical Replication
also use or occupy max_wal_senders ",
so, I suggest the following modification:
Specifies the maximum number of concurrent connections from standby servers
or streaming base backup clients and Logical Replication (i.e., the
maximum number of simultaneously running WAL sender processes). ---please
note ,"and Logical Replication" is newly added。
