The script will be useless to you, besides for referencing what to do.
Export, remove pg15, install pg16, import. I think you can streamline with both installed at once as they correctly version. You could also use the in place upgrade. Aptly named:
pg_upgradeclusters
But updating to 0.19.4, you do not need to go to pg16... but... you should, because of the benefits!
What benefits do you mean?
A faster db. Just the regular performance benefits, https://www.postgresql.org/about/news/postgresql-16-released-2715/
Also, Lemmy is built against v16 (now) so at some point it will eventually no longer JustWork
