Hey quick data modeling question. I'm building an app and would like to capture some other fields on account creation namely username and birthdate. I'm going the self hosted route and using my existing postgresql with the created supertokens db all on the same postgresql instance. Is the recommended model for Supertokens to duplicate the user into my own database on creation and join against that? Would it be better to setup supertokens to write to main db instead of the supertokens db?
