Hi hackers, I tried to understand some implementation details of ProcArray and discovered that this is a bit challenging to do due to a missing comment for PGPROC.pgprocno. E.g. it's hard to understand why ProcArrayAdd() preserves procArray->pgprocnos[] sorted by (PGPROC *) if actually the sorting is done by pgprocno. Took me some time to figure this out.
Here is the patch that fixes this. Hopefully this will save some time for the newcomers. -- Best regards, Aleksander Alekseev
