The routine was coded so as a WAL sender was always used, state required only for one failure test related to START_REPLICATION. This test is changed so as a WAL sender is used by passing a replication option to psql_fails_like(), instead of forcing the use of a WAL sender for all the tests. This has come up as useful in the context of a separate bug fix where we are looking at extending tests for some failure scenarios. These tests need to happen in the context of a normal backend, and not a WAL sender where the extended query protocol cannot be used. Discussion: https://postgr.es/m/aAXkJIOildLUA7vQ@paquier.xyz
