May be worth checking out if Lakebridge supports it yet, https://databrickslabs.github.io/lakebridge/docs/overview/ 

 Not trying to throw a curveball but it could be cool to look into the lakehouse federation: https://docs.databricks.com/aws/en/query-federation/postgresql .

Here's a useful article on someone who's seemingly moved from postgreSQL to Databricks: https://medium.com/mphasis-datalytyx/the-5ds-of-migrating-from-postgresql-to-databricks-705d5df9285e seems like there's a few tips in there. 

@RIDBX I'm looking to following the thread to see how this progresses.

All the best,
