I am trying to restore a previously backed up database .sql file that was created in PostgreSQL 9.6 using pgAdmin4 (I'm not sure which version I was using).

In response to Ron: Do I need to use PG16 instead of pgAdmin4? And if so, can you please provide a website where I can download PG16?

In response to Adrian: How do I determine what version of PostGIS I need to be using? When I installed it, I was only given one option of a version to install.

Since my previous installation of pgAdmin4 was not working, I have started over today, uninstalling all versions of PostgreSQL that I had and reinstalling PostgreSQL Version 17.0 from https://www.enterprisedb.com/ and pgAdmin4 version 8.12 from https://www.pgadmin.org. I tried installing PostgreSQL 9.6.24 also, but I received an error message when I run the installation file: "An error occurred executing the Microsoft VC++ runtime installer." I installed the latest versions of the PostGIS (3.5.0) and psqlODBC drivers (I'm forgot to write that down and am not sure how to check the version). My installation of PostgreSQL/PostGIS was verified as successful. I am able to connect to the PostgreSQL 9.6 and 17 servers. I set the PostgreSQL Binary Path to: C:\Program Files\PostgreSQL\17\bin. I have tried to restore my database using this in the command prompt: "psql.exe db_2024_9 < C:\postgis\db_2017-08-16.sql postgres" using an empty database in both the PostgreSQL 9.6 and 17 servers, and this is the result:

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.
