Describe the bug

Heya, I'm having trouble trying to use different table schema using Supabase for the template refine project

// utility/supabaseClient.ts
export const supabaseClient = createClient(SUPABASE_URL, SUPABASE_KEY, {
    db: {
// problematic part vv
        schema: "custom",
    },
    auth: {
        persistSession: true,
    },
});

That exact code results in the following error.

22:08:57.278    Executing user command: npm run build
22:08:57.892    
22:08:57.892    > data-provider-supabase@3.25.0 build

To Reproduce

1. Get the Supabase refine template
2. Change supabaseClient options schema from "public" to anything else
3. npm run build
4. Error

Expected behavior

Works

System information

• OS: macOS
• Browser (if applies): any
• Version of supabase-js: ^2.7.0
• Version of Node.js: v18.17.1

Additional context

Type '"product"' is not assignable to type '"public"'.ts(2322)
---
(property) schema?: ("public" extends keyof Database ? "public" : string & keyof Database) | undefined

Also npm start works but npm run build doesn't

Running into the same problem. It's a blocker for running Edge Function tests as well if I need to create a client and use data in a non-public schema.

error: TS2322 [ERROR]: Type 'SupabaseClient<any, string, any>' is not assignable to type 'SupabaseClient<any, "public", any>'.
  Type 'string' is not assignable to type '"public"'.
    var client: SupabaseClient = createClient(supabaseUrl, supabaseKey, options) // options has db: { schema: 'my-schema' }
        ~~~~~~

A way to solve this would be to write it like this:

  const supabase = createClient<Omit<Database, "public">>(
    config.SUPABASE_URL,
    config.SUPABASE_SERVICE_ROLE_KEY,
    {
      db: {
        schema: "custom",
      },
    }
  );

It seems that the typing only allow public if public is a key of Database. Otherwise, it would allow the schema to be all possible keys of Database. Hence, the removal of the key public above.
