Right now, WALReceiver has one code path/use case.

Startup has so many, its much harder to know whether we'll screw up one of them.

If we can add it in either place then I choose the simplest, most
relevant place. If the code is the same, we can move it around later.

Let me write the code and then we can think some more.
