Module server 

PostgreSQL wire-protocol listener (Phase 3.1 PG parity).

Accepts TCP connections from PG-compatible clients, drives the startup handshake, and routes simple-query frames into the existing RedDBRuntime::execute_query path. Results are adapted back into PG RowDescription + DataRow frames via types::value_to_pg_wire_bytes.

Phase 3.1 intentionally supports only the simple-query subset; extended query (Parse/Bind/Execute) arrives in 3.1.x once the prepared-statement registry is reusable from this layer.

Structs

PgWireConfig

Startup-tuned configuration for the PG wire listener.

Functions

start_pg_wire_listener

Spawn the PG wire listener. Blocks until the listener errors out. Each connection is handled in its own tokio task.
