8 Upgrading an Installation With pg_upgrade

Without pg_upgrade, to migrate from an earlier version of Advanced Server to Advanced Server 9.5, you must export all of your data using pg_dump, install the new release, run initdb to create a new cluster, and then import your old data. If you have a significant amount of data, that can take a considerable amount of time and planning. You may also have to use additional storage to temporarily accommodate both the original data and the exported data.
The pg_upgrade executable is distributed with Advanced Server 9.5, and is installed as part of the データベース Server component; no additional installation or configuration steps are required.
