Which was explained to you in the comments to the SO question. There is
no 'Installed 16.7 alongside ...'. As was explained this is just minor
version upgrade to Postgres 16 and will only upgrade the binaries and
associated libraries for the major version 16.

I now checked /usr/share/postgresql-common/maintscripts-functions which is installed by the postgresql-common_273.pgdg24.04+1_all.deb package. This script contains the create_main_cluster() function, which according to a comment "skips if any other cluster already exists".

Do man pg_createcluster.
