PostgreSQL docker image based on Alpine Linux

This repo builds a docker image that accepts POSTGRES_USER, POSTGRES_PASSWORD, and POSTGRES_DATABASE env vars, in addition to the same env vars as the official postgres build but with a much smaller footprint. It achieves that by basing itself off the great alpine docker image by GliderLabs.

$ docker run -e POSTGRES_PASSWORD=foo -p 5432:5432 convox/postgres
$ psql -h $(boot2docker ip) -p 5432 -U postgres
Password for user postgres: <foo>
psql (9.4.2)
Type "help" for help.

postgres=#

$ docker images
REPOSITORY          TAG         VIRTUAL SIZE
convox/postgres     latest      26.98 MB
postgres            latest      213.9 MB

Parameterizing POSTGRES_USER, POSTGRES_PASSWORD and POSTGRES_DATABASE is useful for linking containers together.
