I don't know why PITR wouldn't work with BDR, other than you can't use
binary backups across incompatible versions and BDR might be considered
incompatible with community Postgres. I would think it should still work
fine if you try to restore to a BDR server.
That said, remember that if you are not regularly (preferably
automatically) testing your backups by doing a restore and testing the
restore, then you don't have a backup. You have a hope and a prayer. :)
