The "normal" solution is hosted-engine, which has HA - the engine
runs in a VM, and HA daemons monitor it and the hosts, and if there
is a problem they can start it on another host.

There were discussions in the past, which you can find in the list archives,
about running two engines against a single database, and current bottom line
is that it's not supported, will not work, and iiuc will require some
significant development investment to support.

You might manage to have an active/passive solution - install an engine
on two machines, configure both to use the same remote database, but
make sure only one of them is active at any given time. Not sure if that's
considered "fully supported", but might come close.

You can find on the net docs/resources about creating a redundant
postgresql cluster.

Best,
