this has worked and has delivered me 190 records
(I still wonder how they could have happened,
because I only used a stored procedure
with UPDATE - if NOT FOUND - INSERT
Is it maybe pgbouncer's fault?):
id | author | count

(190 rows)
And then I'm trying to construct a query which
would delete the older (the "stamp" column)
of such pairs - but this also doesn't work:
# SELECT id, author, count(1), stamp
FROM pref_rep
GROUP BY id, author, stamp
HAVING count(1) >1;
id | author | count | stamp

Any suggestions please? Should I use a temp table here?
Thank you
