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.

## Summary by CodeRabbit

* **New Features**
* The API settings page now warns when the authenticator role’s exposed
schemas differ from the saved Dashboard configuration.
* You can reset the override to restore the saved schema configuration.
The reset requires permission and provides success or error feedback.

How it works

Supabase is a combination of open source tools. We’re building the features of Firebase using enterprise-grade, open source products. If the tools and communities exist, with an MIT, Apache 2, or equivalent open license, we will use and support that tool. If the tool doesn't exist, we build and open source it ourselves. Supabase is not a 1-to-1 mapping of Firebase. Our aim is to give developers a Firebase-like developer experience using open source tools.

Architecture

Supabase is a hosted platform. You can sign up and start using Supabase without installing anything. You can also self-host and develop locally.

Architecture

  • Postgres is an object-relational database system with over 30 years of active development that has earned it a strong reputation for reliability, feature robustness, and performance.
  • Realtime is an Elixir server that allows you to listen to PostgreSQL inserts, updates, and deletes using websockets. Realtime polls Postgres' built-in replication functionality for database changes, converts changes to JSON, then broadcasts the JSON over websockets to authorized clients.
  • PostgREST is a web server that turns your PostgreSQL database directly into a RESTful API.
  • GoTrue is a JWT-based authentication API that simplifies user sign-ups, logins, and session management in your applications.
  • Storage a RESTful API for managing files in S3, with Postgres handling permissions.
  • pg_graphql a PostgreSQL extension that exposes a GraphQL API.
  • postgres-meta is a RESTful API for managing your Postgres, allowing you to fetch tables, add roles, and run queries, etc.
  • Envoy is a cloud-native, high-performance edge and service proxy.

Client libraries

Our approach for client libraries is modular. Each sub-library is a standalone implementation for a single external system. This is one of the ways we support existing tools.
