You can technically use the Python to write back to Postgres if you are comfortable putting your creds into the code window. The downside of this is your creds would be viewable to anyone you share the workbook with.
We have gotten a lot of requests for write-back-to-DB (Snowflake, Postgres, etc) so will be adding first-class support for this feature soon that will use the same connection creds which are stored encrypted in KMS and are not viewable to people you share the workbook with.
Would love to chat about your use-case if you want to reach out to us at contact[at]rowzero.io
