I think this should already be covered by: https://github.com/supabase/postgres-meta/pull/1035/changes#diff-c903ec71df16a8ae5f665c19c21b273f74c2f8eb02f5e8a3552ebe69d18be18fR196-R198 🤔

This needs to be tested with the inference within https://github.com/supabase/supabase-js/tree/master/packages/core/postgrest-js as I expect this might break a few things.

I remember having to use never specifically here to be able to detect the difference between actual functions with args, and functions with no args. Using a Record<string, never> in my memory didn't allowed that.

let returnType = getFunctionReturnType(schema, fn)

// Check for specific error cases
