Great. Is this a general solution for multi-step queries, too?

Prepared statements are also related to stored function support.  Is
there any impact on support for that?

Thanks,

commit 01f9d0376f95f08f352f96f0f1bdda8c56b610a8

    Allow commands PREPARE and EXECUTE to prepare a statement and execute it resp.
    DEALLOCATE is already allowed.
    Adds support for parameterised queries. While setting the statement names in
    RemoteQuery node, we also set the parameter types. These are used while sending
    Parse message to data nodes. The infrastructure to bind the parameter values was
    already there.
