pg_dump -X

Back in 2006, we have this commit:

commit 2b25e1169f44368c120931787628d51731b5cc8c
Author: Peter Eisentraut <peter_e@gmx.net>

   The -X option in pg_dump was supposed to be a workaround for the lack of   portable long options.  But we have had
portablelong options for a long   time now, so this is obsolete.  Now people have added options which *only*   work
with-X but not as regular long option, so I'm putting a stop to this:   -X is deprecated; it still works, but it has
beenremoved from the   documentation, and please don't add more of them.
 

Since then, two additional -X options have crept in, doubtless due to
mimicry of the existing options without examination of the commit
logs.  I think we should either (a) remove the -X option altogether or
(b) change the comment so that it clearly states the same message that
appears here in the commit log, namely, that no new -X options are to
be created.  The existing comment says that -X is deprecated, but that
doesn't make it entirely 100% clear that the code isn't intended to be
further updated, at least judging by the results.
