# First of all, we copy postgres server from the official postgres image,
# since 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.
