Yes, almost. I need the list of all different rows.
It's syntax error at the *.
ROW(*)

Hi,
I would like to select the count of distinct rows in a table.
SELECT COUNT(DISTINCT *) FROM mytable;
This does not work. How can I do it with Postgres?
Thanks,
Otto
I guess what you need is to know how many times a single row is
duplicated so i think what you need is something like this:
SELECT fld1, COUNT(DISTINCT fld1)
FROM (SELECT ROW(*) as fld1 FROM mytable) AS foo
GROUP BY fld1;
