Hi,

do I understand correctly that a BackendId is just an index into the ProcSignalSlots array and not (necessarily) the same as the index into ProcArrayStruct's procs?

If yes, could these be synchronized? Why is ProcSignalSlot not part of PGPROC at all? Both are shared memory structures per backend (plus NUM_AUXILIARY_PROCS). What am I missing?

Regards

Markus Wanner
