Using different schema for Supabase prevents build, results in error

Bug report

• I confirm this is a bug with Supabase, not with my own application.
• I confirm I have searched the Docs, GitHub Discussions, and Discord.

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
22:08:57.892    > tsc && refine 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.
