Upgrading an installation with pg_upgrade v15
Note
Review the upgrade considerations prior to performing an upgrade with the pg_upgrade utility.
While minor upgrades between versions are fairly simple and require only installing new executables, past major version upgrades were both expensive and time consuming. pg_upgrade eases migration between any version of EDB Postgres Advanced Server (version 9.0 or later) and any later release of EDB Postgres Advanced Server that's supported on the same platform.
Using pg_upgrade can reduce both the amount of time and the disk space required for many major-version upgrades.
