Perfectly viable. However, the WAL files must exist for this to happen. So you need to set wal_keep_segments
appropriately,or set up WAL archiving.
Note that you could even provide a more up-to-date database for your people to work with. If the testbed is nearly up
todate, then an rsync to update it would take very little time. So you could shut down the replica, rsync, and bring
thereplica back up.
