I have a use case where I'd like to reconstruct a Simple Query message and pass it back to my user. To do this I'd want to make a few changes to theClient::simple_query() implementation.

1. Store and return the entireField that is built from a backendMessage::RowDescription inSimpleQueryRow instead of just returning the column name inSimpleColumn. I've done this with minor changes to the current interface inour rust-postgres fork.

2. Ideally, exposeSimpleQueryRow::body to avoid having to read each value usingSimpleQueryRow::get() and re-serialize the message to bytes myself.

3. Ideally, create public constructors forSimpleQueryRow,Field, andDataRowBody to allow easier unit testing in my own code. I noticed that a similar question came upin a previous issue. Maybe we could implement this under a compile time feature flag?
