Because this is a clear thinko. pgstat_bestart_final() is always a
code path taken after pgstat_beinit() for auxiliary processes and the
rest of the world. I am pretty sure that my intention here was to
use the argument and not MyProcNumber in the function
pgstat_create_backend() because we rely on MyProcNumber to be defined
when the create routine is called, and that's what
pgstat_bestart_final() offers as guarantee, due to pgstat_beinit().
There is no bug currently, but let's clean that up in all the branches
anyway for clarity and any future back-patch. Hence, what do you think
about the attached?
