There are any community implementation for reading/saving Dataframes from/to a Postgres DDBB? Or any other SQL DDBB? Thanks!

Hi Rubén! Dagster has multiple database I/O managers that you can draw inspiration from. I'll use the DuckDB one as an example: 1. Here is the raw base class you can inherit from that we use for our database I/O managers 2. Here is the DuckDB I/O manager 3. Here is the type handler that manages the data from DuckDB as a Pandas Dataframe a. If you move up the file tree a bit, you'll see type handlers for Polars and PySpark too
