Comment:
I resolve this issue when digging into nested KeyTransform.
== Root Cause
1. When using nested KeyTransform, it concatenate child keys in the wrong
format, i.e. a list `[child1, child2]`
2. Instead, according to pgsql, it should be a string like `'{child1,
child2, ...}'`
== Solution
After updating the as_sql() transformation, the issue is resolved. Will
send PR soon.
