sql (PostgreSQL): schema update:
- added version check on top of update files, SQL will not be applied if the version is not the one expected
- new db schema version (3)
- added "presence" access_model in nodes
- added "schema" column in nodes
- converted items data to xml, this will allow the use of all XML functions
PostgreSQL now needs to have been compiled with --with-libxml .
