The example code below gives the following error in the final select:
SELECT: no such binary operator 'sql_add(boolean,boolean)'
The query is supported by other databases and is (afaik) valid sql.

mclient -d monetdbtest -s 'drop table t' || true
mclient -d monetdbtest -s 'create table t ("v1" int,"v2" int, "v3" int)'
mclient -d monetdbtest -s 'insert into t ("v1","v2","v3") values (1,1,1)'
mclient -d monetdbtest -s 'insert into t ("v1","v2","v3") values (1,2,1)'
mclient -d monetdbtest -s 'insert into t ("v1","v2","v3") values (1,2,3)'
mclient -d monetdbtest -s 'insert into t ("v1","v2","v3") values (4,4,4)'
mclient -d monetdbtest -s 'select * from t where (("v1" > 1)+("v2" > 1)+("v3" > 1)) > 1'
