Post Description

I wanted to brush up my SQL skills and was looking for an online course that included a live DB.

Most PostgreSQL courses require you to create an account or pay. This is probably because they have to bear the costs of running a full server-side database.

So I created learnpg.xyz, a collection of PostgreSQL SQL exercises that run client side.

Sharing here because it might be of use to people!
