    Make the transaction level advisory locks cluster aware. This is
    part2 of the earlier commit that introduced cluster-awareness to
    session-level advisory locks.

commit 6a5bdc57325c9a584ab66386fa6bbf54372e4986

    Fix for deferred constraints
    
    Basics for DEFERRED constraints were not working for 2 reasons.
    1) There was a bug with the management of transaction-related parameters
    (parameters that can be used only inside a transaction block like SET
    CONSTRAINT and SET LOCAL). When a transaction parameter was set in a
    transaction block, it was correctly sent down to remote nodes where
    connections were already in hold, but if new connections were obtained
    the transaction parameter on hold was sent to remote node before any
    BEGIN query, resulting in having no effects.
    2) If an implicit prepare failed, remote nodes were not correctly
    rollbacked, resulting in remote connections keeping locks on prepared
    relations. This could result by a stale state if for example a DDL was
    involved in transaction.
    
    Patch by Abbas Butt, review and some improvements by me.
