Hmm, I can't see how you got that state without there being some sort of
error messages.

Just to be clear:

1) The 9.6 and 14 instances where installed from the same source?

2) Are you using tablespaces other then the default?

Scan the Postgres log for the 14 instance at /var/log/postgresql for
error messages.
