Can anyone please help me?

Uh, your binary is at /usr/lib/9.6/bin/psql but you are specifying the
LD path as /usr/lib/postgresql/9.6/lib. Maybe try:

LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/9.6/lib

The problem is clearly using the wrong version of the libpq libary.

How did you install Postgresql?  If by the package manager, what packages
did you install?

Apparently psql is linking to a pre-9.6 copy of libpq.so. You could
confirm that with
ldd /usr/lib/9.6/bin/psql

I tried setting it didn't help; export
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/postgresql/9.6/lib

(1) Are you sure there's a more up-to-date libpq.so there?
That path doesn't seem to square with where you say psql is.

(2) Possibly you need to put the 9.6 directory first not last.

(3) If that still doesn't work, you need to configure the system's
dynamic linker to look there. You really want to do that anyway,
as messing with LD_LIBRARY_PATH all the time is no fun.
See "man ldconfig".

Hi Tom ;

Thank you for your detailed email.

You're absolutely right i have bad linking for it to old version 9.5 in the
same node.

You mean linking like 9.5 as below right ?

libpq.so.5 => /usr/lib/postgresql/9.5/lib/libpq.so.5 (will add version 9.6
link ,too if i got it right)

(3) If that still doesn't work, you need to configure the system's
dynamic linker to look there. You really want to do that anyway,
as messing with LD_LIBRARY_PATH all the time is no fun.
See "man ldconfig".

I tried but i think i missed something.

Appreciate it.
