I also test it with postgresql9.6.3 and pg_rman
1.3.4(https://github.com/ossc-db/pg_rman/releases/download/v1.3.4/pg_rman-1.3.4-pg96.tar.gz).
However, it has the same problem.
In my view, pg-rman just do PITR which contains pg_start_backup,copy files
and pg_stop_backup steps,it will not affect the tuple page theoretically.
