It badly hallucinated in my test. I asked it "Rust crate to access Postgres with Arrow support" and it made up an arrow-postgres crate. It even gave sample Rust code using this fictional crate! Below is its response (code example omitted):
I can recommend a Rust crate for accessing PostgreSQL with Arrow support.
The primary crate you'll want to use is arrow-postgres, which combines the PostgreSQL connectivity of the popular postgres crate with Apache Arrow data format support.
This crate allows you to:
Query PostgreSQL databases using SQL
Return results as Arrow record batches
Use strongly-typed Arrow schemas
Convert between PostgreSQL and Arrow data types efficiently
