Yes.

If we used PID then we'd eventually have 64K (or whatever the range of
PIDs is on your platform) different pg_temp_nnn entries cluttering
pg_namespace.  But we only need MaxBackends different entries at any one
time.  So the correct nnn value is 1..MaxBackends.  BackendId meets the
need perfectly.
