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.

TIP 2: you can get off all lists at once with the unregister command
(send "unregister YourEmailAddressHere" to [EMAIL PROTECTED])
