pgproxy
pgproxy is a flexible proxy for the Postgres wire protocol that allows for customizing authentication and backend selection by breaking apart the startup message flow between frontend and backend.
Once authenticated, it falls back to being a dumb proxy that simple shuffles bytes back and forth.

Functions ¶
func AuthenticateClient ¶ added in v0.18.0
AuthenticateClient tells the client they've successfully authenticated.
func CopySteadyState ¶ added in v0.18.0
CopySteadyState copies messages back and forth after the initial handshake.
func FinalizeInitialHandshake ¶ added in v0.18.0
func FinalizeInitialHandshake(client *pgproto3.Backend, server *pgproto3.Frontend) (*pgproto3.BackendKeyData, error)
FinalizeInitialHandshake completes the handshake between client and server, snooping the BackendKeyData from the server if sent. It is nil if the server did not send any backend key data.
func SendCancelRequest ¶ added in v0.18.0
func SendCancelRequest(conn io.ReadWriter, req *pgproto3.CancelRequest) error
func SetupServer ¶ added in v0.18.0
SetupServer sets up a frontend connected to the given server.
