I am having trouble finding documentations on what this methods returns. I know for a SELECT query it will return an iterable object (although I can''t find any documentation on that). I am doing a DELETE query. When executed this should return the number of affected rows, which is the best way to tell if the query worked. I''m also doing a COPY query. Is there any way to get this result? I am using postgres, so the result is a PGresult object, but that object does not respond well to .inspect and has no docs. Thanks.
