CLI type generation and UUIDs

When I run

npx supabase gen types typescript > database.types.ts

npx supabase gen types typescript > database.types.ts

, all my primary and foreign keys that are UUIDs in SQL become

string

string

in TypeScript.

Is there a way to make this a TS UUID type? (Other than redefining all columns in my TS app — not really an option given the amount of foreign keys in use).

Or are there good reasons to not want this? I guess the query itself also results in type string? Do we know if there is a specific reason for that?

The reason I ask is that the following does not give a type error, but it does give a PostgREST error:

createClient()
.from('users')
.select('*')
.eq('id', '') // ❌ gives a 400 error

createClient()
.from('users')
.select('*')
.eq('id', '') // ❌ gives a 400 error

So when I accidentally set a default value to emtpy string rather than

null

null

, my app began firing requests and throwing errors.
