Monica Khoury 123c768de1 Warn when authenticator role overrides exposed schemas (FE-4472) (#50982)
## What

Adds a warning in Project Settings > API when the `authenticator` role's
`pgrst.db_schemas` setting overrides the Dashboard's "Exposed schemas"
configuration, plus an inline "Reset override" button to fix it in one
click.

## Why

`ALTER ROLE authenticator SET pgrst.db_schemas = ...` silently overrides
what PostgREST actually exposes, regardless of what's selected in the
Dashboard. Users hit a confusing PGRST106 error with no indication that
a role-level override is the cause.

## How

- New query (`authenticatorRoleConfigQueryOptions`) reads
`pg_roles.rolconfig`
for the `authenticator` role and parses out any `pgrst.db_schemas`
value.
Configured to always refetch on mount and window focus, since the fix is
often applied outside the Dashboard (SQL editor, another client) with no
  cache-invalidation event for the app to react to.
- `PostgrestConfig.tsx` compares that value against the currently
selected
  schemas and shows an `Admonition` warning naming the actual overriding
  schemas, with a link to the PGRST106 troubleshooting guide, when they
  differ.
- The warning includes a "Reset override" button that runs
  `alter role authenticator reset pgrst.db_schemas` after a confirmation
  step (showing the exact SQL that will run, with a copy button), then
  refetches so the warning clears immediately without a page reload.

## Testing

1. In the SQL Editor of a test project, run:
   ```sql
   alter role authenticator set pgrst.db_schemas = 'public';
   ```
2. Go to Project Settings > API, and select a schema other than (or in
   addition to) `public` in "Exposed schemas" (e.g. add `api`).
3. The new warning should appear, naming `public` as the schema actually
   in effect, with a link to the PGRST106 troubleshooting guide.
4. Click "Reset override" in the warning, confirm in the modal, and
check
   that the warning clears immediately without a page reload.
5. Alternatively, clear the override manually from the SQL editor:
   ```sql
   alter role authenticator reset pgrst.db_schemas;
   ```
then navigate away from the API settings page and back (or refocus the
   browser tab) — the warning should clear without a hard refresh.

Supabase Studio

A dashboard for managing your self-hosted Supabase project, and used on our hosted platform. Built with:

What's included

Studio is designed to work with existing deployments - either the local hosted, docker setup, or our CLI. It is not intended for managing the deployment and administration of projects - that's out of scope.

As such, the features exposed on Studio for existing deployments are limited to those which manage your database:

  • Table & SQL editors
    • Saved queries are unavailable
  • Database management
    • Policies, roles, extensions, replication
  • API documentation

Managing Project Settings

Project settings are managed outside of the Dashboard. If you use docker compose, you should manage the settings in your docker-compose file. If you're deploying Supabase to your own cloud, you should store your secrets and env vars in a vault or secrets manager.

How to contribute?

  • Branch from master and name your branches with the following structure
    • {type}/{branch_name}
      • Type: chore | fix | feature
      • The branch name is arbitrary — just make sure it summarizes the work.
  • When you send a PR to master, it will automatically tag members of the frontend team for review.
  • Review the main contributing guide to help test your feature before sending a PR.
  • The Dashboard is under active development. You should run git pull frequently to make sure you're up to date.

Developer Quickstart

Note

Supabase internal use: To develop on Studio locally with the backend services, see the instructions in the internal infrastructure repo.

# You'll need to be on Node v22
# in /studio

## For external contributors
pnpm install # install dependencies
pnpm run dev # start dev server

## For internal contributors
## First clone the private supabase/platform repo and follow instructions for setting up mise
mise studio  # Run from supabase/platform alongside `mise infra`

## For all
pnpm run test # run tests
pnpm run test -- --watch # run tests in watch mode

Running within a self-hosted environment

Follow the self-hosting guide to get started.

cd ..
cd docker
docker compose -f docker-compose.yml -f ./dev/docker-compose.dev.yml up

Once you've got that set up, update .env in the studio folder with the corresponding values.

POSTGRES_PASSWORD=
SUPABASE_ANON_KEY=
SUPABASE_SERVICE_KEY=

Then run the following commands to install dependencies and start the dashboard.

npm install
npm run dev

If you would like to configure different defaults for "Default Organization" and "Default Project", you will need to update the .env in the studio folder with the corresponding values.

DEFAULT_ORGANIZATION_NAME=
DEFAULT_PROJECT_NAME=
