I think Peter's wrong here, for two reasons:
* The comment tells you what undecorated "wal_sender_timeout = 60" will
do.
* The comment tells you what the precision of the setting is. For
instance, archive_timeout is in seconds; you can try setting it to "10ms"
if you like, but that won't do much for you.
We could imagine making these points moot, by disallowing inputs that lack
units and converting all time GUCs into some common scale (requiring
wider-than-int storage) ... but that seems sufficiently non backward
compatible that I don't see it happening. It's not clear that it'd be a
usability improvement anyway.
