No, a postgres database consists entirely of the files in the data directory.
If the database process is set up properly to read those files either with -D
on startup or the PGDATA environment variable then you're done.

But you do have to be very careful to never have both nodes up at the same
time. If they are I think your database will quickly be corrupted. And both
nodes have to be the same architecture and compiled the same way.
