    postgresql plugin: Added a plugin to collect PostgreSQL database statistics.
    
    This plugin collects active server connections, transaction numbers, block IO
    and table row manipulations of PostgreSQL databases. For this purpose it keeps
    persistent connections to all configured databases. The statistics are
    collected from PostgreSQL's "statistics collector" subsystem.
    
    Currently, statistics are collected from the pg_stat_database,
    pg_stat_user_tables and pg_statio_user_tables views. The following new types
    have been introduced: pg_blks, pg_n_tup_c, pg_n_tup_g, pg_numbackends, pg_scan
    and pg_xact. The type names are basically the same as the column names in the
    queried views to keep things consistent. For the number of tuples, counter and
    gauge values exist, so the type names have been prefixed with "_c" and "_g"
    respectively.
    
    Sample plugin configuration:
    
      <Plugin postgresql>
        <Database foo>
          Host "hostname"
          Port "5432"
          User "username"
          Password "secret"
          SSLMode "prefer"
          KRBSrvName "kerberos_service_name"
        </Database>
        <Database bar>
          Service "service_name"
        </Database>
      </Plugin>

    src/utils_complain: Changed c_release() into a macro.
    
    While the c_complain*() functions are usually used in error conditions only,
    c_release() is usually used whenever things went right (which should be the
    more common case ;-)). In order to minimize the overhead in the latter case,
    c_release() has been changed into a macro which checks if the complaint
    actually has to be released and calls c_do_release() in that case. This
    function then takes care of reporting the release-message (this is the
    original implementation of c_release()). So, we remove the overhead of a
    function call in the usual case, i.e. when we don't have to report any
    messages.
