SimpleQuery request to 'SET TIME ZONE' generates an exception

[Jerry-Carter]

try conn.simpleQuery("SET TIME ZONE INTERVAL '+5:45' HOUR TO MINUTE").wait()

This line generates a message with identifier 'S' and produces an exception in PostgresSimpleQuery::respond(to:). Specifically,

throw PostgresError.protocol("Unexpected message during simple query: \(message)")
