Creating a prepared statement for a delete generates a fatalError

[Jerry-Carter]

Prepared statements that do not return values appear to generate a fatalError.

database.prepare(query: "DELETE FROM my_table WHERE "MyIndex" = $1").wait()

Postgres responds with a message of type 110 (.noData) which trips the default case at

postgres-nio/Sources/PostgresNIO/Connection/PostgresDatabase+PreparedQuery.swift

Line 82 in 7c195a4

fatalError("Unexpected message: \(message)")
