Crate postgresql_protocol 

PostgreSQL wire protocol: message encoding/decoding, type OIDs, and the authentication state machine.

This crate is intentionally free of any async runtime. It operates on [bytes::BytesMut] buffers and is shared between the postgresql client and the compile-time query macros, so both understand the protocol from a single implementation.
