Hello Wyat, thanks for the link. The PostgreSQL version is not an issue, this has been upgraded to 9.6 recently. The ticket assumes everything will be done online while the Puppet masters are running etc.
Actually, I would just do it with a maintenance window and take all puppet masters offline. Than upgrade PuppetDB through the versions from above, update the termini on the masters and start everything again. As the PDB HTTP API completely breaks between 2.x and 3.x, there will be an interruption anyway for users. My main concern were the database migrations run by PuppetDB during the upgrade, which seems not to be an issue (despite the ancient version).
