Thanks for your feedback.  This is not about GIDs at all, but just about 
identifying a transaction.  I'm out of ideas on how else to phrase that. 
  Any suggestion?

Maybe we should not try to give examples and reference other systems, 
but just leave it at:

      The <parameter>ctx</parameter> parameter has the same contents as for
      the other callbacks. The parameters <parameter>xid</parameter>
      and <parameter>gid</parameter> provide two different ways to identify
      the transaction.  The later <command>COMMIT PREPARED</command> or
      <command>ROLLBACK PREPARED</command> carries both identifiers,
      providing an output plugin the choice of what to use.

That is sufficient an explanation in my opinion.   What do you think?
