How RECOVER affects real-time statistics

After recovery to the current state, the in-memory counter fields are still valid, so Db2 does not modify them. However, after a point-in-time recovery, the statistics might not be valid.

Consequently, Db2 sets all the REORG, STATS, and COPY counter statistics, as well as TOTALROWS and TOTALENTRIES, to null after a point-in-time recovery.
