I've just build 3.2 on a clean Ubuntu 18.4. Installer (-n) complains like this:
Archiveopteryx requires PostgreSQL 9.1.0 or higher (found only 10.3). Is this trying to tell me: - it doesn't work on 10.x, or - the way it does the check is a bit broken ? OK I could check the latter - but the former is a straight question.
