Single quotes must always be escaped as they are used for any text literals at CrateDB.

Thanks. So that serialization will need further improvements to treat OBJECT values the same like above.

key_value = "'" + json.dumps(key_value) + "'::OBJECT"

elif isinstance(key_value, list) and key_value and isinstance(key_value[0], dict):
key_value = "'" + json.dumps(key_value) + "'::OBJECT[]"

constraint = f"{self.DATA_COLUMN}['{key_name}'] = {key_value}"
constraints.append(constraint)
