PostgreSQL for Odroid

Dear Sirs,

I have been working with PG-SQL database on Windows platform. Recently I bought my first Linux computer Odroid XU3
Lightwith Ubuntu 14.04. 
So I tried to download PostgreSQL from
http://apt.postgresql.org/pub/repos/apt/dists/trusty-pgdg/InRelease
, but it failed:
------------------------
$ apt-get update
...
W: Failed to fetch http://apt.postgresql.org/pub/repos/apt/dists/trusty-pgdg/InRelease  Unable to find expected entry
'main/binary-armhf/Packages'in Release file (Wrong sources.list entry or malformed file) 
------------------------

Documentation for version 9.1.14 lists ARM as a supported platform.
http://www.postgresql.org/docs/9.1/static/supported-platforms.html

Should I try another source? Please help me.

Kind regards
