The `analyze_new_cluster.sh` script output by `pg_upgrade` just runs `vacuumdb --all --analyze-in-stages`, which runs three passes over the database, getting better stats each time. Each of these passes is independent; the third pass does not require the first two. `--analyze-in-stages` is only provided to get "something" into the database, on the theory that it could then be started and used. Since we wait for all three passes to complete before starting the database, the first two passes add no value. Additionally, PosttgreSQL 14 and up stop writing the `analyze_new_cluster.sh` script as part of `pg_upgrade`, suggesting the equivalent `vacuumdb --all --analyze-in-stages` call instead. Switch to explicitly call `vacuumdb --all --analyze-only`, since we do not gain any benefit from `--analyze-in-stages`. We also enable parallelism, with `--jobs 10`, in order to analyze up to 10 tables in parallel. This may increase load, but will accelerate the upgrade process.
