synapse/docker/complement/Dockerfile

# This dockerfile builds on top of 'docker/Dockerfile-workers' in matrix-org/synapse
# by including a built-in postgres instance, as well as setting up the homeserver so
# that it is ready for testing via Complement.
#
# Instructions for building this image from those it depends on is detailed in this guide:
