Supabase

I'm not sure if anyone has already mentioned this, but is there any documentation or articles with lots of working code for RLS?

This is a Postgres thing, so if you do a google search for Row Level Security with Postgres, you should find a bunch of articles.

Thank you very much. I'll give it a try !

The first link explain a lot of the concepts quite well, the second link is a bit more advanced but you should be able to get some useful information from it.

This one shows off the advanced use quite well https://www.cybertec-postgresql.com/en/using-row-level-security-to-make-large-companies-more-secure/

I had mistakenly thought that RLS was a Supabase specific feature. I just looked it up as you suggested and now I have a lot of information. Thank you. I will also read the article you sent me.

Yeah a lot of things outside of Auth and Storage are just Postgres features with a UI built on top of them.
