Example is broken

[Sandr0x00]

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

The code in /example just does not work. There are multiple issues. (Only test_postgres_changes was relevant for me, so I ignored the others)

• The example code uses the data from tests folder without stating it somewhere
• test_postgres_changes tries to subscribe to id=eq.10 but id is a uuid
• test_postgres_changes blocks infinitely => test_presence will never be executed
• Only a delete query triggers the callback, INSERT and UPDATE don't for some reason. (might be related to Python realtime with RLS #86, but unsure why delete than works)

To Reproduce

Steps to reproduce the behavior, please provide code snippets or a repository:

1. Go to 'example'
2. Use migration from /tests/supabase/migrations/20240810125543_init.sql as /example/supabase/seed.sql
3. npx supabase start
4. Execute poetry run python app.py

Expected behavior

A working example, which developers can check and learn from.
