Server-side network protocol
summary
Prototype server implements Postgres v3 on the wire using Erlang, demonstrating concrete decoding and encoding code, a connection handler that coalesces/splits TCP chunks, and a separate protocol state machine built with gen_statem. Examples show binary pattern matching to parse length-prefixed messages, use of i/o lists to avoid memcpy, handling ambiguous authentication tags, and returning correct row description/data/command-complete sequences; the prototype works and exposes performance and metadata-integration tradeoffs.
