PG::UndefinedTable: ERROR: relation "pg_range" does not exist

I am following the guide here:

Install Discourse on Windows 10 for development

This tutorial has been tested on Windows 10 and 11. So you want to set up a development environment for Discourse on Windows 10 (or windows 11)? You can do it easily using Windows Subsystem for Linux feature. It is faster too . This setup requires the WSL 2 installation. It is only available in Windows 10 builds 18917 or higher. We’ll assume that you already installed Windows Subsystem for Linux 2 (Ubuntu) on your Windows 10 system. WARNING: Install Ubuntu 1…

When I run bundle exec rake db:create it just errors out and says:

[Warning] Discourse recommends developing using Ruby v3.1.3 or above. You are using v2.7.6.

What do I do?
I am using WSL 2 and Ubuntu 18.04.5, and PostgreSQL version 9.2

@joecooldoo

PostgreSQL version 9.2

That’s very old.

You should be running 13.x nowadays.

[joecooldoo]

Alright, I’ll try upgrading.

[merefield (Robert)]

Not sure it’s the source of your problem, but it will definitely be more compatible

Now I have this error:

According to that SO link you either have an old or corrupt database.

[joecooldoo]

How do I create a new one, then? I have never used PostgreSQL before.

[joecooldoo]

Well, now I’m getting a different error:

[Warning] Discourse recommends developing using Ruby v3.1.3 or above. You are using v2.7.6.
We could not find your database: postgres. Which can be found in the database configuration file located at config/database.yml.

To resolve this issue:

- Did you create the database for this app, or delete it? You may need to create your database.
- Has the database name changed? Check your database.yml config has the correct database name.

To create your database, run:

        bin/rails db:create

So I descided to follow this guide:

Install Discourse for development using Docker

Developing using Docker Since Discourse runs in Docker, you should be able to run Discourse directly from your source directory using a Discourse development container. Pros: No need to install any system dependencies, no configuration needed at all for setting up a development environment quickly. Cons: Will be slightly slower than the native dev environment on Ubuntu, and much slower than a native install on MacOS. Step 1: Install Docker Ubuntu curl -fsSL https:/…

I get this error after the “migrating database”

I’m still having problems with this, any solutions?
