I investigated the packets that the rust postgres driver sends, and when using the extended protocol, a query executed when using an extended protocol execution method first sends a packet for the parse, and then combines the bind and execution in the next packet.

This is understandable for when using a prepared statement, however when the used query is not a prepared statement, this should be possible to reduce in a singe call? I just looked at the java packets, and JDBC seems to perform this in one packet.

This can mean a significant reduction of overhead for small queries where client response time is mostly composited of network times of flight, and potentially reduces CPU.

I have investigated the query method for as extended protocol execution and extended protocol with prepared statement, and the simple_query method for simple query protocol.
