Documentation of pg_badkend_pid and stats functions

Two questions: Why is pg_backend_pid documented with the stats
functions (9.19 System Information Functions) seems more logical.

Also, I can see mentioning the stats functions in the monitoring
section, but shouldn't they actually be documented in with the rest
of the functions?
