No, because the external pidfile has zero to do with Postgres' internal
behavior.
Personally I always thought that the external pidfile was a "feature"
we should have rejected. It can never be a particularly reliable guide
to what PG is doing, the more especially so if the program looking at it
isn't doing any cross-checking, as the OP seems not to be doing.
