The code in Thuban 1.0.0 only works with tables that have a column
called "gid".  This has been fixed in CVS last week.  You might want to
try that.

It doesn't have to.  The requirement for the gid-column is (or was now)
really a bug in Thuban.  All that's required now is that it has an
integer column with ids.  The dialog lets you choose which one to use.
