`statement error` test should fail when expected error did not occur

[xiangjinwu]

Reproduce: With PostgreSQL running on port 5432,

sqllogictest -p 5432 -d test -u $USER <(echo $'statement error\nselect 1;')

Expected: [FAILED]: query is expected to error but did not

Actual: [OK]

Practical usage:

statement error
select power(-1, 0.5);

I can reproduce. BTW, query error is correct.

Thank you. Seems query error is an undocumented extension?
