It does smell like the aggregate output has been corrupted by the time it got to the plpgsql function. I don't particularly want to try to synthesize a test case from the essentially-zero SQL-level information we've been provided, though. And I doubt we can track this down without a test case. So please try to sanitize the case you have enough that you can share it. regards, tom lane
