newbie question: ERROR: getattproperties: no attribute tuple 1259 -2

Hi,

I'm getting this weird error when using the \d or \dd command. This same
error also pops up when I try to do anything in pgaccess. This is PostgreSQL
7.0.2 on LinuxPPC. I tried wiping out the whole installation, reinstalling,
rebooting the whole machine, starting with a fresh install and fresh
database. Still I can't seem to get this error to go away. I don't see
anything about this error in the manuals (I did a full text search!).

Here's a little transcript of the action. I created a database called test1,
a new table, then added a few rows. So it seems like I can hobble by as long
as I don't use pgaccess or the \d command with an argument ... but it would
be nice to use them (and know everything's right). Thanks for any help...
