PostgresNode::start() doesn't work for servers older than version 10, either. If I hack that function to sleep until the postmaster.pid file exists, it works, but that is really ugly and is just to prove to myself that it is a timing issue. There were a few commits in the version 10 development cycle (cf, commit f13ea95f9e473a43ee4e1baeb94daaf83535d37c) which changed how pg_ctl works, though I haven't figured out yet exactly what the interaction with PostgresNode would be. I'll keep looking.
