The files belonging to this database system will be owned by user "_postgresql".
This user must also own the server process.
The database cluster will be initialized with locale "ja_JP.UTF-8".
initdb: could not find suitable text search configuration for locale "ja_JP.UTF-8"
The default text search configuration will be set to "simple".
Data page checksums are disabled.

If pg_upgrade fails after this point, you must re-initdb the

Upgrade Complete
----------------
Optimizer statistics are not transferred by pg_upgrade.
Once you start the new server, consider running:
/usr/local/bin/vacuumdb -U postgres --all --analyze-in-stages
Running this script will delete the old cluster's data files:
./delete_old_cluster.sh
