selecting rows based on unique fields in a column - Mailing list pgsql-novice

Hi,
    Is there an easy way to select all rows which have a single entry in a
particular column from those that have multiple entries.

At present I'm using

   select reqitem from lasting
group by reqitem having count(reqitem) = 1;

But this gives me only reqitem column and I want the rest of the row!

I can see how to do this by creating another table updating it with the
above and then selcting into the table all the rest of the row, but is
there an easier way, have I missed something obvious?

Thanks for any response.
