                 The syntax of this parameter in the DB_CONFIG file is
                 a single line with the string repmgr_add_remote_site, 
                 one or more whitespace characters, and the host, port and
				optional peer parameters specified. Where host is the site's host identification string, generally a TCP/IP host name; 
				port is the port number on which the remote site is receiving. For example:
				
repmgr_add_remote_site exmample.com 49201 peer
