There seems to be an automatism in your application that wraps every statement in a subtransaction to emulate statement-level rollback. That will cause severe performance problems: https://www.cybertec-postgresql.com/en/subtransactions-and-performance-in-p= ostgresql/ So your application is broken not only because it does not close its transactions.
