Crate akar_postgres 

PostgreSQL extension for Akar.

Provides integration with PostgreSQL databases using the native tokio-postgres crate with a synchronous wrapper via block_on.

Native Rust approach

Uses tokio-postgres (v0.7) with futures::executor::block_on() to bridge the async PostgreSQL client with Akar’s synchronous runtime. Most complex extension due to catalog binding + table enumeration + type mapping.
