Thank you. I started to play with it a little bit, since I think it's an
interesting idea. And there are already few notes:

* I don't see a CF item for that, where is it?

* Looks like there is a sort of sensitive typo in `postgresql.conf.sample`:

```
+#causal_reads_standy_names = '*' # standby servers that can potentially
become
+ # available for causal reads; '*' = all
+
```

it should be `causal_reads_standby_names`. Also I hope in the nearest
future I
can provide a full review.
