I'm trying to use avpops with unixodbc.

What's the format of the avp_uri for unixodbc?

The documentation has:
modparam("avpops","avp_url","mysql://user:passwd@host/database")

What format do I use? Is it this? Is it something else?
modparam("avpops","avp_url","unixodbc://user:passwd@host/database")

Why isn't this documented?
