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?

1) You can copy/paste the error message and provide as text.

2) Assuming you are installing Postgres 16 from the EDB package, the
from here:

https://www.postgresql.org/download/windows/

PostgreSQL Version 64 Bit Windows Platforms
16 2022, 2019

[...]
11 2019, 2016, 2012 R2
10 2016, 2012 R2 & R1, 7, 8, 10

3) From here:

https://www.enterprisedb.com/downloads/postgres-postgresql-downloads

9.6 can still be downloaded.

It is not a supported version, but you can at least use it to access
your database.

4) You need to provide a more detailed explanation of what you are
trying to achieve.

5) 9.6 -> 16 is six major version jump. That means some research needs
to be done, starting with determining what version of PostGIS you need
to be using.
