(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, and
we can not display a database-encoding of B_server when \l is used.)
