4. What did you do?
5. What did you expect to see?
6. What did you see instead?

We are trying to run some queries that return arrays. We expect to get the results back as a Python list, but instead we get the database's raw string response. For example, SELECT TO_ARRAY(1) should return [1]. However, we are actually receiving the following:

"[
  "1"
]"

Here is a basic program that reproduces the problem: https://gist.github.com/csdev/4d7078af2b0ab927865a0c0a71f535ad

7. Can you set logging to DEBUG and collect the logs? https://gist.github.com/csdev/7c1fd49083e239f97c9b4dc5263d97b5
