You cannot just replace the binaries to upgrade from an earlier major version to 16.X. The release notes use "a
dump/restore(is/is not) required" to indicated whether you can just replace the binaries ("is not") and restart the
serveron the same database files.
Dump/restore is not the only option for a major version upgrade. You can use the pg_upgrade utility that is part of
thestandard distribution, or logical replication to a new server on the new version.
