I am not sure whether this change is necessary because the error message
will appear in the log of the standby server and users can easily know
the connection user just by checking primary_conninfo.

However, if we need this change, how about using
"DETAIL: The connection user "r1" must have the REPLICATION attribute."
This pattern is used in other part like check_object_ownership() and
AlterRole(). The user name is not included there, though.
