https://github.com/docker-library/postgres/ is where the official
postgres images are managed. Previously we were compiling from
source, but now it uses the packages from postgresql.org, which makes
it simpler to have all the current versions. It is available on the
hub as postgres.

A few minor suggestions:
(1) RUN apt-get update && apt-get install -y package package; That
way you get a natural cache bust if you change the list of packages.
It could be formatted as follows:

RUN apt-get update \
&& apt-get install -y -q postgresql-9.4 postgresql-client-9.4
postgresql-contrib-9.4 \
&& apt-get install -y -q postgresql-plpython-9.4 \
&& ...
or
RUN apt-get update && apt-get install ...
RUN apt-get update && apt-get install ...
or
RUN apt-get update && apt-get install -y -q \
autoconf \
build-essential \
postgresql-9.4 \
postgresql-client-9.4 \
...

(2) Combine multiple RUN lines so that you can clean up unnecessary
files. I would change `RUN wget RUN tar RUN ./configure...` to `RUN
wget | tar && cd && ./configure && make && make install` with some new
lines and backslashes for readability. That way the tar does not get
permanently saved into a layer of the image. Even a `RUN rm ...tar.gz`
would just add another layer and the tar would still take space in the
layer stack.

I would suggest sticking with a stable version of postgres rather than
the beta. And it should make things simpler for you.
