In response to Help with restoring database from old version of PostgreSQL  (Catherine Frock <frock@uwalumni.com>)

1. PG16 will read a PG 9.6 backup file, so there's no need to install PG 9.6.
2. Installing PG on a OneDrive share is certainly a Very Bad Idea.
3. PG is not the same as PgAdmin.

Yes, I still have the backup file. I tried to open pgAdmin4 today to see what version I'm running, and now this happened (see attachments). My operating system is Windows 10 Home, version 10.0.19045 Build 19045. I installed Postgres using these instructions: https://basille.org/postgis2017/installation_instructions/install_postgresql.html I'm guessing at this point I probably need to start all over with the installation since pgAdmin4 is not working? 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?

Thank you for your help,

Do you still have the Postgres 9.6 instance running?

What version of pgAdmin4?

So the 9.6 instance is running.

What OS and version are you running?

How did you install Postgres?
