 ## Postgres Database
 In this project, I'm using a Postgres database to store user information. The database is hosted on cloud in the [supabase](https://supabase.com/), and the server communicates with it using the [libpq](https://www.postgresql.org/docs/9.1/libpq.html) library.

+| ----------- | --------- | ----------- |

+| name        | TEXT      | User's name. |
