You can call stored procedures as a "Remote Procedure Call".
That's a fancy way of saying that you can put some logic into your database then call it from anywhere. It's especially useful when the logic rarely changes - like password resets and updates.
final data = await supabase
.rpc('hello_world');
final data = await supabase
.rpc('echo_city', params: \{ 'name': 'The Shire' \});
