This is primarily useful for making tests of this utility more deterministic, to avoid the complexity of starting pg_receivewal as a deamon in TAP tests.
While this is less useful than the equivalent pg_recvlogical option, users can as well use it for example to enforce WAL streaming up to a end-of-backup position, to save only a minimal amount of WAL.
Use this new option to stream WAL data in a deterministic way within a new set of TAP tests.
