Re: pg_stat_bgwriter.buffers_backend is pretty meaningless (and more?)

I found that the 'standalone backend' backend type is not documented 
right now.
Adding something like (from commit message) would be helpful:

Both the bootstrap backend and single user mode backends will have 
backend_type STANDALONE_BACKEND.
