Henrik Jonsson 8f8c0bbc52 Explicitly set uid/gid for postgres/postgres ...

The values 999:999 are identical to the current user/group id assigned
in the containers (tested in postgres:9.4, but should be identical for
all versions), but this guarantees that those values will remain the
same even if the groupadd/useradd commands were moved elsewhere in the
Dockerfile, or a new debian:jessie image was pushed.

Tested:
core@test-1 ~ $ docker run -v $(pwd):/origin --rm -it debian:jessie bash -c 'groupadd -r postgres --gid=999 && useradd -r -g postgres --uid=999 postgres && mkdir /origin/pg && chown -R postgres:postgres /origin/pg'
core@test-1 ~ $ ls -hsal pg/
total 8.0K
4.0K drwxr-xr-x 2  999  999 4.0K Sep 22 12:57 .
4.0K drwxr-xr-x 5 core core 4.0K Sep 22 12:59 ..

core@test-1 ~ $ rm -rf pg/
core@test-1 ~ $ docker run -v $(pwd):/origin --rm -it --user=root postgres:9.4 bash -c 'mkdir /origin/pg && chown -R postgres:postgres /origin/pg'
core@test-1 ~ $ ls -hsal pg/
total 8.0K
