Already the first query
select
ref_17.progress as c0,
cast(coalesce(ref_17.tag,
ref_17.tag) as oid) as c1
from
sys.queue as ref_17
where false
limit 156;
triggers the assertion on an empty virgin database.

The second query triggers a syntax error:
syntax error, unexpected LIMIT, expecting UNION or EXCEPT or INTERSECT or ')' in: "select
(select event from sys.triggers limit"

The syntax error is "correct" by MonetDB standards: "limit" (and "offset"?) are not allowed in subqueries.

The assertion has been fixed. The syntax errors won't be.
