postgresql.conf WAL options

I was talking to Tom Lane yesterday about our current postgresql.conf
WAL options and we came up with the following TODO items I just added:

---------------------------------------------------------------------------

* Reorder postgresql.conf WAL items in order of importance
* Remove wal_files postgresql.conf option because WAL files are now recycled
* Find proper defaults for postgresql.conf WAL entries
* Add checkpoint_min_warning postgresql.conf option to warn about
checkpoints that are too frequent
