Hi Adrian,
Command \l gives the list of db available DBs in the cluster including template0 and template1, I can connect to other DBs and run queries as well.
My motive is just to upgrade pgsql from 9.6 to 13 using the pg_upgrade command.
Regards,
Ajay

First I would determine what else might be missing?
In psql what happens if you do:
\l
to get a list of databases?
And can you connect to the databases other then postgres?

When was the backup done and how?
Are you sure it is a complete backup?
Do you have tablespaces,other then the default, in use?
