I checked the patch with Chap cases. The patch fixes handling of
boolean, number types which mentioned in the wiki.

I have a few comments related to the code and the documentation. I
attached the patch, which fixes it.

There is an example in the documentation:

SELECT xmltable.*
   FROM xmlelements, XMLTABLE('/root' PASSING data COLUMNS element text);
        element
----------------------
    Hello2a2   bbbCC

With the patch XMLTABLE returns different result now.

copy_and_safe_free_xmlchar() function should be hid by #ifdef
USE_LIBXML, otherwise I get an error if I build the Postgres without
--with-libxml.

There is a comment within XmlTableGetValue(). I changed it, mainly I
used Markus patch from the related thread mentioned by Alvaro.

Please see the changes in the patch.
