Sorry, not enough caffeine.  What I should have said was that Hot
Standby could put stronger requirements on what gets put into WAL than
archiving for recovery does.  Heikki's proposal upthread was
wal_mode='standby' versus wal_mode='archive' (versus 'off'), which
seemed sensible to me.

We realized some time ago that it was a good idea to separate
archive_mode (what to put in WAL) from archive_command (whether we are
actually archiving right now).  If we fail to apply that same principle
to Hot Standby, I think we'll come to regret it.
