(Example)
A_server(6.5.3) B_server(7.0) | | ---+------------+------------+---- network
| C_server(7.0) + terminal
* Telnet-login is not permitted in A_server and B_server.* Telnet-login is permitted in C_server.(We use C_server's
psql)
In this case, we can not use \l and \df command for A_server.
Should we use 6.5.3 as a C server?
(If we use 6.5.3-psql, we can not use \df command for B_server, andwe can not display a database-encoding of B_server
when\l is used.)
