Go here:

https://postgis.net/development/source_code/

and look in the release notes. They will tell you what range of Postgres 
versions are supported. For instance the latest 3.5.0:

https://git.osgeo.org/gitea/postgis/postgis/raw/tag/3.5.0/NEWS

"To take advantage of all postgis_sfcgal extension features SFCGAL 1.5+ 
is needed. PostgreSQL 12-17 required. GEOS 3.8+ required. Proj 6.1+ 
required. "

1) Is db_2017 a database you had on old server?

2) What backup did you do in pgAdmin4 for the 9.6 instance?

Did you do the entire server:

https://www.pgadmin.org/docs/pgadmin4/8.13/backup_server_dialog.html

or backup just one database?:

https://www.pgadmin.org/docs/pgadmin4/8.13/backup_dialog.html

If the latter then you did not get the global objects for the Postgres 
9.6 instance. This includes roles(users) and would account for the user 
errors.

To get the global objects use:

https://www.pgadmin.org/docs/pgadmin4/8.13/backup_globals_dialog.html

But if 9.6 is no longer supported, can I still use it to access my database? I assumed I would need to migrate to the most recent version of PostgreSQL, but maybe that was a wrong assumption?
