6b8772a33e Update Data API docs to include explicit grants (#42969)
Updates our documentation pages around the Data API to include
instructions on how to grant the necessary privileges across API roles
across tables and functions. Current behaviour means this is largely
unnecessary as privileges are granted by default on public schema, but
adding instructions will help cover scenarios where this isn't the case
and expose some of the underlying magic happening.

## To test:
- These updates refer to new settings that are added to the data api
that give more visibility and control over what tables and functions are
accessible via the api.
- To view these settings you'll need enable `tableEditorApiAccessToggle
` feature flag

<StepHikeCompact.Details title="Create a Supabase project">
Go to [database.new](https://database.new) and create a new Supabase project.
Alternatively, you can create a project using the Management API:
</StepHikeCompact.Details>
<StepHikeCompact.Code>
```bash
# First, get your access token from https://supabase.com/dashboard/account/tokens
export SUPABASE_ACCESS_TOKEN="your-access-token"
# List your organizations to get the organization ID
curl -H "Authorization: Bearer $SUPABASE_ACCESS_TOKEN" \
https://api.supabase.com/v1/organizations
# Create a new project (replace <org-id> with your organization ID)
curl -X POST https://api.supabase.com/v1/projects \
-H "Authorization: Bearer $SUPABASE_ACCESS_TOKEN" \
-H "Content-Type: application/json" \
-d '{
"organization_id": "<org-id>",
"name": "My Project",
"region": "us-east-1",
"db_pass": "<your-secure-password>"
}'
```
</StepHikeCompact.Code>
<StepHikeCompact.Details>
When your project is up and running, go to the [**Table Editor**](/dashboard/project/_/editor) section of the Dashboard, create a new table and insert some data. Then in the [**Integrations > Data API**](/dashboard/project/_/integrations/data_api/settings) section of the Dashboard, expose the specific tables or functions you want to access. To automatically grant access for new tables and functions in `public`, enable **Default privileges for new entities**.
Alternatively, you can run the following snippet in your project's [SQL Editor](/dashboard/project/_/sql/new). This will create an `instruments` table with some sample data.
</StepHikeCompact.Details>
<StepHikeCompact.Code>
```sql SQL_EDITOR
-- Create the table
create table instruments (
id bigint primary key generated always as identity,
name text not null
);
-- Insert some sample data into the table
insert into instruments (name)
values
('violin'),
('viola'),
('cello');
alter table instruments enable row level security;
-- Enable read access for the Data API
grant select on public.instruments to anon;
```
</StepHikeCompact.Code>
<StepHikeCompact.Details>
Make the data in your table publicly readable by adding an RLS policy:
</StepHikeCompact.Details>
<StepHikeCompact.Code>
```sql SQL_EDITOR
create policy "public can read instruments"
on public.instruments
for select to anon
using (true);
```
</StepHikeCompact.Code>
