URGENT - "CANNOT EXTEND"

A couple days ago I asked what happens when I hit 2GB and I was told "no
worries". Well, I hit 2GB and it barfed on me. It looks like postgres is
trying to create a new file, but it isn't able to use it....

/dev/sda is where my database resides and it has 38% free.

Right now, geocrawler is still up and running, but no new mail can be
inserted into it until I can get this figured out....

Please respond directly to tim(at)perdue(dot)net

Thanks,

Tim
