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 .
