to reasonably test master/standby setups on a single machine is pretty
jarring (yes, one can use basebackup tablespace maps - but that doesn't
work well for new tablespaces).

+1 agree. Feature which can't be easily tested becomes hurdle for development and this is one of them. For reference the bug reported in [1] is hard to test and fix without having easy ability to setup master/standby on same node. We discussed few ways to eliminate the issue in thread [2] but I wasn't able to find a workable solution. It would be really helpful to lift this testing limitation.
