Ok, did that. Here's an updated patch:

* made incorrect combinations of wal_mode and
archive_mode/max_wal_senders throw an ERROR instead of WARNING

* renamed wal_mode to wal_level

* reworded the documentation changes a bit

This doesn't contain any changes to pg_start_backup() yet, that's a
separate issue and still under discussion.

At commit, should I bump catversion, or PG_CONTROL_VERSION, or both? The
patch replaces the unlogged-operation WAL record with a record
containing current parameter values, and it changes pg_control. I'm
guessing both.
