We rely on pg_config to find where PostgreSQL is installed to setup and
start postgres on our own in the tests setup script.

You don't need PostgreSQL to build Gnocchi (I'm not sure what build
means for Python). You just need it to run unit/integration tests and to
build the documentation – because the doc is built by making real
requests to a real server and printing the reply in the doc.

I hope it helps, but feel free to ask if not!
