Re: Help with restoring database from old version of PostgreSQL

I'm seeking help in restoring a database that was created with PostgreSQL 9.6. I backed it up successfully and have restored it before, but that was when PostgreSQL 9.6 was still supported. After going through the installation of PostgreSQL 16.3, I opened up pgAdmin 4 to try to verify the PostgreSQL/PostGIS installation, but when I try to connect to the PostgreSQL 16.3 server, I get an internal server error message:   'ServerManager' object has no attribute 'user_info'.

In pgAdmin4, I am able to connect to the PostgreSQL 9.6 server, but when I try to verify the install by querying: CREATE EXTENSION postgis;

SELECT postgis_version();

I get the following error message:  ERROR: could not open extension control file "C:/Program Files/PostgreSQL/9.6/share/extension/postgis.control": No such file or directory SQL state: 58P01

How can I restore my database to have access to it again?
