i have question regarding the new presentity index. there is now
<index>
<name>udee_presentity</name>
<colref linkend="username"/>
<colref linkend="domain"/>
<colref linkend="event"/>
<colref linkend="etag"/>
<unique/>
</index>
<index>
<name>ude_presentity</name>
<colref linkend="username"/>
<colref linkend="domain"/>
<colref linkend="event"/>
<unique/>
</index>
why is the second index needed, because my understanding is that at
least in mysql the second index is already included in the first?
