Add more debugging information when dropping twice pgstats entry
Floris Van Nee has reported a bug in the pgstats facility where a stats
entry already dropped would get again dropped. This case should not
happen, still the error generated did not offer any details about the
stats entry getting dropped.
This commit improves the error message generated to inform about the
stats entry kind, database OID, object OID and refcount, which should
help to debug more the problem reported. Bertrand Drouvot has been
independently able to reach this error path while writing a new feature,
and more details about the failure would have been helpful for
debugging.
