Installing matrix-synapse on pypy

sudo apt install virtualenv
virtualenv -p ./pypy3 ~/synapse/env
source ~/synapse/env/bin/activate
pip install --upgrade pip
pip install --upgrade setuptools
sudo apt install libjpeg-dev libxslt-dev libxml2-dev postgresql-server-dev-all
pip install matrix-synapse[all]

Currently, this is working. However, adding rooms is causing issues but only with some rooms. The error generated looks like this.

If I switch to a regular version of python to add the room and then switch back to pypy, I can talk to the room just fine.

There's a definite decrease in utilization using pypy. Check out these graphs.
