        ADMIN CONNINFO - preamble - identifying PostgreSQL database


        NODE ival ADMIN CONNINFO =      DSN     ; [ ival;] [ ’conninfo’]


        Describes  how  the  slonik  utility  can reach a nodes database in the
        cluster from where it is run (likely the DBA’s workstation).  The  con‐
        ninfo  string  is  the string agrument given to the PQconnectdb() libpq
        function. The user used to connect must be the special replication  su‐
        peruser,  as some of the actions performed later may include operations
        that are strictly reserved for database superusers by PostgreSQL.
        The slonik utility will not try to connect to a given  database  unless
        some subsequent command requires the connection.
               As  mentioned  in the original documents, Slony-I is designed as
               an enterprise replication system for data centers. It  has  been
               assumed  throughout  the  entire  development  that the database
               servers and administrative workstations involved in  replication
               and/or setup and configuration activities can use simple authen‐
               tication schemes like ‘trust’.  Alternatively,  libpq  can  read
               passwords from .pgpass .
               If  you  need to change the DSN information for a node, as would
               happen if the IP address for a host were  to  change,  you  must
               submit  the new information using the STORE PATH(7) command, and
               that configuration will be propagated. Existing  slon  processes
               may need to be restarted in order to become aware of the config‐
               uration change.
        For more details on the distinction between this and STORE PATH(7), see
        “ Slony-I Path Communications” [not available as a man page].
