How does it handle multi-row result sets? The expectation with other
Postfix databases is that the results will be combined with
comma-separators. I don't see where that logic is in the code...
Can you explain:

And returning no rows is definitely normal and expected, and you should
then (as you do) return a NULL result.

It does appear to the db_common parser infrastructure:
