Re: Extensibility of the PostgreSQL wire protocol

After implementing this three different ways inside the backend over the years, I landed on almost this identical approach for handling the MySQL, TDS, MongoDB, and Oracle protocols for NEXTGRES.

Initially, each was implemented as an background worker extension which had to handle its own networking, passing the fd off to new protocol-specific connections, etc. This worked, but duplicate a good amount of logic. It would be great to have a standard, loadable, way to add support for a new protocol.
