Unable to see postgresql 9.6 after adding postgresql repository

[Amey Abhyankar <sco1984@gmail.com>]

Hello,

I want to upgrade postrgesql 9.4 to 9.6 in Debian Jessie.
I added following repo at /etc/apt/sources.list.d
URL ref = http://apt.postgresql.org/pub/repos/apt/dists/jessie-pgdg/

After adding, I performed apt-get update.
Now,
I use following command to check available versions = dpkg-query -l postgresql*
I can see older postgresql versions & version 10.
But I can not see 9.6 version in the list.
However,
If I visit = http://apt.postgresql.org/pub/repos/apt/dists/jessie-pgdg/
I can see 9.6 folder.
I tried to add repo as = deb http://apt.postgresql.org/pub/repos/apt/
jessie-pgdg 9.6
But no luck.

How to proceed? Any thoughts/suggesions? Thanks.

Regards,
Amey.
