Supabase is changing the default for Data API exposure of public tables and has replaced the legacy anon key with publishable keys on new projects. Updating the guide so it works under both old and new defaults.

  • Document the upcoming Data API grants change and add explicit grants to the schema SQL
  • Merge schema, grants, and RLS into one SQL block
  • Note that publishable keys replace the anon key in new projects

AI disclaimer: Used Claude to verify the documentation changes. I set up a brand new Supabase project and PowerSync instance to test the guide end to end too.
