Upgrade Complete
----------------
Optimizer statistics are not transferred by pg_upgrade.
Once you start the new server, consider running:
/opt/pgsql/pg140/bin/vacuumdb --all --analyze-in-stages
Running this script will delete the old clusters data files:
./delete_old_cluster.sh

/opt/pgsql/pg140/bin/pg_ctl start -D /data/pg140
/opt/pgsql/pg140/bin/vacuumdb --all --analyze-in-stages
