I don't seem to be breaking that so a bit confused? And if I use a username that's already taken (username has the unique constraint) I get this error PostgresError: duplicate key value violates unique constraint "user_username_unique", and I can't import the type PostgresError as it's not exported but it's part of the types in the node modules, yet I can't import it without runtime errors. What's the standard for handling sql errors like this? SyntaxError: The requested module 'postgres' does not provide an export named 'PostgresError'
