Hi guys.

Is upgrade from ver. 13 to 16 possible?

-> $ sudo -u postgres pg_upgrade -D /var/lib/pgsql/data/

You must identify the directory where the old cluster
binaries reside.
Please use the -b command-line option or the PGBINOLD
environment variable.
Failure, exiting

Or is a restoration from a backup the only way?

many thanks, L.
