If we're going to add it to pg_stat_*, why is 'backend' part of the
name? All the existing backend_* function fetch some piece of data
about a given backend -- whereas this function does not (it takes
no arguments).

IMHO, a better name would be something like 'backend_process_id()',
or 'unix_pid', or 'backend_pid()'.

Also, can you add some documentation on this?

Cheers,

Neil
