Hi,

Currently when the pg_createsubscriber error out and exit in between
execution, the standby server started by the pg_createsubscriber may
still be running. I think this standby server should be stopped at
exit of pg_createsubscriber(when it errors out), as this server is
started by pg_createsubscriber and it may be running with
configurations that may not be desired by the user (such as " -c
listen_addresses='' -c unix_socket_permissions=0700"). Thoughts?

Added a top-up patch v28-0005 to fix this issue.
I am not changing the version as v28-0001 to v28-0004 is the same as above.

Thanks and regards,
Shlok Kyal
