How to use PostgreSQL offline local storage on a React-Native app?

I'm creating my first app and I'd want to keep using the stack I've learned. Therefore I've created a React-Native app that has an Express server and a PostgreSQL database. I can connect to a server that already exists (for instance, using my localhost server on Windows) but I can't figure out how to create a database server per device or some kind of PostgreSQL local storage. Is there no solution? Is there no way to use a local port on an Android/IOs device as it's used on Windows?

I left a list of posts that I've read but couldn't find an answer.

• Most exhaustive answer and plenty of solutions but no one using something like Postgres/SQL or related

  • What are my options for storing data when using React Native? (iOS and Android)

• No answer (just an alternative) and it's an old question:

  • Is it possible create and query a local Postgres database on an Android device?

• Same as before (answer is to use Realm):

  • App local database

• More suitable but is there no answer and it's written in Java.

  • Can't connect Android application to local PostgreSQL database

• Remote access (not local storage) but following the d-vine answer it seems possible:

  • React Native - connect to PostgreSQL database

• Postgres's docs on creating a database server:

  • https://www.postgresql.org/docs/14/server-start.html

Edit: added all this related post on local storage

• A lot of question about local storage and almost all answers saying to use AsyncStorage:
