Hi, In order to run `collect.py`, it seems I need to have a psql database setup with mimic-iv FHIR loaded. I have installed psql and have mimic-iv FHIR downloaded and unzip and stored in a folder. Do you know how to load them into a database called 'mimiciv_fhir'? <img width="1751" alt="image" src="https://github.com/user-attachments/assets/69ba7f9d-131b-4164-b2e3-75dcbfca296c">
