I understood you were working on making PostgresNode compatible with older
versions of PostgreSQL. So ou can create and interact with older versions,
eg. 9.0. Did I misunderstood?

My set of class had the exact same goal: creating and managing PostgreSQL nodes
from various major versions. It's going a bit further than just init() though,
as it supports some more existing methods (eg. enable_streaming) and adds some
others (version, switch_wal, wait_for_archive).
