	// DialTimeout bounds the backend dial. Defaults to 5s.
	DialTimeout time.Duration
	// StartupTimeout bounds the entire startup phase (SSL/GSS negotiation +
	// StartupMessage). A client that connects and dribbles bytes — or sends
	// nothing — is dropped after this, freeing the goroutine+fd it pins.
	// Defaults to 10s; the deadline is cleared once relaying begins.
	StartupTimeout time.Duration
	// MaxConns caps the number of connections handled concurrently. When the
	// cap is reached, further accepts are refused fast (connection closed)
	// rather than queued unbounded. Defaults to 256.
	MaxConns int
	// IdleTimeout closes a relayed session that has seen no bytes in either
	// direction for this long, reclaiming abandoned-but-open connections.
	// Defaults to 15m.
	IdleTimeout time.Duration
	// TLSConfig, when set, makes the proxy answer SSLRequest with 'S' and
	// upgrade the client connection via a server-side TLS handshake before
	// the startup message. When nil (default) SSLRequest is answered 'N' and
	// the session stays plaintext. Backend dials are always plaintext
	// (branches are local/cluster-internal).
