Hi,
I have found a bug in PostgreSQL doing "except all".
It removes some records which it shouldnt when I run except on large data
sets. If I run the same except only on the records in question (using
where...), it shows up in the result ok.
I have put the data and small python code here:

Thank you in advance,
