    Resolve build issue for Solaris related to new event metrics.
   
    Max reports that the Solaris compiler really wants some bit
    flag manipulations (esp. 1<<31) to be done only on unsigned
    integers.  Resolved this, and fixed a couple of other places
    in this code where signed values were used for no compelling
    reason (best fix it now before its too late!).

    Update the postgresql PMDA to resolve issue with recovery metrics.
   
    The initial version of this code was suboptimal wrt fetching the
    postgresql recovery metrics on a database which is_in_recovery.  In
    this mode, the current_xlog_position metric is unavailable, and the
    way the SQL was structured, the fetch for all recovery metrics was
    failing.  Split this into two separate value fetches and the values
    are available always, whenever they exist (depends on host state in
    terms of active/in_recovery).
