Multiple VHost with Postgresql

Hello,

We have THREE domains (xmpp.domain1,com, xmpp.domain2.com and xmpp.domain3.com). I've configured "ejabberd.yml" with the three HOSTS and their config sections (please see the config section below). The thing is that when I config ONLY a vHost and comment the others, it works because I can register every user to its domain-->database.

I mean, if I execute:
ejabberdctl register userX xmpp.domainX.com userXpass

I can see the new userX created in the database X. But this only works when there is only an activated HOST at the same time. If I activate the three vHosts, ejabberd only creates the user in the first database (dbDomain1).

Did I explained myself? Do you know how to activate the three vHosts so that their users are created in their correspondant Database?
Thank you!
