While you're trying to *connect*? That's hard to believe. I would think
only table creation or addition of a column would cause an attempt to
add an entry to pg_attribute_attrelid_index.

Hard to tell. Try updating to a more recent version of Postgres --- in
recent releases (7.0.3 and up), this message includes the specific
kernel error code that's being returned by write().
