Server version detection

See original GitHub issue

A question for the library’s gurus…

Is there anything within the PostgreSQL connection protocol that would provide in indication as to the server’s version and/or features, without having to execute SELECT version()?

Here’s the thing: I need to auto-replace every SELECT * FROM proc_name() with CALL proc_name() - the new syntax added in PostgreSQL v11, so I need to know what server version we are connected to, without having to execute a separate SELECT version() for it.

I don’t think any part of pg uses the ParameterStatus startup messages yet, but they are parsed and should be emitted on the connection as a 'parameterStatus' event. server_version is one.

A custom Client type that extends pg.Client is one way (maybe not the simplest) – you can add the listener in the constructor.
