While running the code : uv run pgcli -h localhost -p 5432 -u root -d ny_taxi from this section: https://github.com/DataTalksClub/data-engineering-zoomcamp/blob/main/01-docker-terraform/docker-sql/05-data-ingestion.md I ran into this error : ImportError "no pq wrapper available" when importing psycopg3 however when i run : uv add "psycopg[binary,pool]" That fixes the issue and is the recommended way to install psycopg according to the official docs. https://pypi.org/project/psycopg/ A slight modification is required for the ingest_data.py script to expressly tell SQLAlchemy to use the psycopg3 version installed and not fall back to psycopg3. will submit another pr for the ingest_data script separately. why psycopg3? It works well and better with >= Python3.13, which the Docker image relies on.
