Hue Creates Many Connections to PostgreSQL

[#1]

Hi,

I'm using Hue editor to send queries to PostgreSQL  database.
I have configured interpreter in the following way:

[notebook]

    [[interpreters]]

    [[[postgresql-7af1c4ea51]]]

      name=devops-notification

      interface=sqlalchemy

      options='{"url": "postgresql://${USER}:${PASSWORD}@dbname.eu-central-1.rds.amazonaws.com:5432/notification"}'

It works fine.  But every time I send a quiery, new connection to PostgreSQL instance is established. 
Is there a way to use single database connection per user or just close connections right it returned a result?

Thanks  in advance.

@Andrii I doubt if it's possible. Check the document if this helps:
