That would make the command a great deal slower, since it would have to
access each sequence to get that info. I don't object to adding such
columns to \ds+, but I don't think it's a good idea to put them in the
basic command.
The other problem you're going to have here is that there is in fact no
such command as "\ds" (nor "\ds+"); rather, it's a special case of
\dtsvi. As such, putting any relkind-specific info into the result is
problematic. I think you're going to have to invent a different command
if you want there to be sequence-specific columns.
