Hm.  Actually this seems like an argument for exposing MyBackendId, since
what pg_stat_activity really depends on is BackendId.  But as that view
is presently defined, you'd not be able to writeWHERE backendid = my_backend_id()
because the view doesn't expose backendid.

*Please* don't call it pg_backend_id --- that invites confusion with
BackendId which is a different thing.

I'd suggest pg_backend_pid.
