The only utilities "psql and pgadmin" of 9.6 can be used with 10.0 server, but the rest of all utilities cannot be used with 10.0. server

Thank you in advance.

Thank you Shreeyansh!

Do you know anything about libraries?

In particular libpq (v9.6 towards v10.0).

Thanks.

imho: you have to re-check the new improvements[1] :

some examples:

* "Declarative table partitioning" ( as I know, you can't see all information from psql9.6 )
* "Stronger password authentication based on SCRAM-SHA-256" ( if the security is the first priority )

scram-sha-256
The method scram-sha-256performs SCRAM-SHA-256 authentication, as described in RFC 7677. It is a challenge-response scheme that prevents password sniffing on untrusted connections and supports storing passwords on the server in a cryptographically hashed form that is thought to be secure.
This is the most secure of the currently provided methods, but it is not supported by older client libraries.
https://www.postgresql.org/docs/10/static/auth-methods.html

* changes in sequences ( "a new pg_sequence system catalog" ; "The output of psql's \d command for a sequence has been redesigned, too." )

* changes in "psql" Client Application

Imre

Note that psql is purposefully kept compatible with previous server
versions, so it should work without issue.  If it does not, please
report it as a bug.
