Whether there's a good way depends on what you're already doing. If
you're going to the trouble of making a backup using PITR anyway, it's not
hard to stop applying new logs to that replica and dump from it to get a
point in time backup across all the databases. That's kind of painful now
because you have to start the server to run pg_dumpall, so resuming
recovery is difficult, but you can play filesystem tricks to make that
easier.
