Build Identifier:

skinkie@chamechaude ~ $ /opt/monetdb-aug2016/bin/mclient -d htm
create table test (test text);
insert into test values ('123:456:789');
select split_part(test, ':', 2) from test;
+----------------+
| splitpart_test |
+================+
| 456 |
+----------------+
1 tuple (4.606ms)

Now with copy into:

copy (select split_part(test, ':', 2) from test) into '/tmp/export/htm/test.csv' DELIMITERS ',' NULL AS '';
1 affected row (3.772ms)

cat /tmp/export/htm/test.csv
"123:456:789","456"

The input for the function is duplicated in the output.

Reproducible: Always

this is caused by the split_project optimizer. Now we handle this exception.
