[Devel] presence tables inconsistent

[Klaus Darilion]

Hi!

There are 2 tables/columns where XML content is stored. These use 
different column types:

                 |  postgres  |   mysql
----------------+------------+------------
presentity.body |   bytea    |   text
xcap_xml.xcap   |   text     |   text

I wonder why we use bytea in postgresql only in presentity table. If 
there is a problem with text in presentity table, but not in xcap_xml 
table then I guess the problem is not the column type but somewhere else.

IMO we should try to be more consistent.
