From docs:
https://www.postgresql.org/docs/12/functions-conditional.html#FUNCTIONS-COALESCE-NVL-IFNULL
"The COALESCE function returns the first of its arguments that is not
null. Null is returned only if all arguments are null. ..."
So if it returned NULL/None then the first and second values both
resolved to NULL.
