Re: DISTINCT ON not working...?

This is a temporary table (with no indexes) that gets created in the same
transaction block as the SELECT gets run, but I tried creating an index on
the ean column anyway with no luck:

CREATE INDEX ean_idx ON TMPTABLE USING btree (ean);
SELECT DISTINCT ON (ean)
ean,
count(*)
FROM TMPTABLE
WHERE code NOT IN (SELECT code FROM stock_deleted)
AND ean IS NOT NULL
GROUP BY ean;

Still returns:
3246576919422 2

Wild guess - have you tried reindexing this table? I haven't seen
corrupted indexes since 7.1, though - it usually means subtle hardware
problems.
