Add information about "generation" when dropping twice pgstats entry
Dropping twice a pgstats entry should not happen, and the error report generated was missing the "generation" counter (tracking when an entry is reused) that has been added in 818119afccd3. Like d92573adcb02, backpatch down to v15 where this information is useful to have, to gather more information from instances where the problem shows up. A report has shown that this error path has been reached on a standby based on 17.3, for a relation stats entry and an OID close to wraparound.
