-- A frequent question in IRC is how to delete rows that are duplicates over a set of columns, keeping only the one with the lowest ID.
-- This query does that for all rows of tablename having the same column1, column2, and column3.


DELETE FROM tablename
WHERE id IN (SELECT id
              FROM (SELECT id,
                             row_number() over (partition BY column1, column2, column3 ORDER BY id) AS rnum
                     FROM tablename) t
              WHERE t.rnum > 1);

In addition to Kevin Conner's answer: block arguments do not support the same semantics as method arguments. You cannot define default arguments or block arguments.

This is only fixed in Ruby 1.9 with the new alternative "stabby lambda" syntax which supports full method argument semantics.
