eek! group names are limited to 16 characters.
that bites.

I think we can just bump it in the groups table: 
(remember, use the postgres user, not root)

the easiest way to increase the length of a column, 
is to do a database dump, edit the dump, and then 
re-import it. unfortunaly, the postgres ascii dump
doesn't dump blobs. while we're safe now, this is 
potentially eitful

there's some information about how I did this in the
rtadmin queue. I forget which ticket.
