This is awesome, thanks for creating this. I've had to write some absolutely wonky scripts to dump a PostgreSQL database into Parquet, or read a Parquet file into PostgreSQL. Normally some terrible combination of psycopg and pyarrow, which worked, but it was ad-hoc and slightly different every time.

A lot of other commenters are talking about `pg_duckdb` which maybe also could've solved my problem, but this looks quite simple and clean.

I hope for some kind of near-term future where there's some standardish analytics-friendly data archival format. I think Parquet is the closest thing we have now.
