# first of all, we create a base image with a postgres server and database,
# which we can copy into the target image. For repeated rebuilds, this is
# much faster than apt installing postgres each time.
#
# This trick only works because (a) the Synapse image happens to have all the
# shared libraries that postgres wants, (b) we use a postgres image based on
# the same debian version as Synapse's docker image (so the versions of the
# shared libraries match).
# now build the final image, based on the Synapse image.
