JSONB sqlalchemy Aggregate Function

Question

With SQLAlchemy I want to reproduce the available aggregate function jsonb_object_agg from a subquery sq_objects:

from sqlalchemy import select,         


        

Answer 1

Not the most elegant implementation, but since I now the labels of the subquery columns; a raw text input solves the issue:

func.jsonb_object_agg(
    text("sq_objects.keys"),
    text("sq_objects.values")
).over(
    partition_by=sq_objects.c.object_id).label("attributes"),
