[fivetran-jamie]

Are you a Fivetran customer?

nope!

Is your feature request related to a problem? Please describe.

No, just want to roll out postgres + databricks compatibility for our most popular packages. **Describe the solution you'd like** make it compatible with both! **Please indicate the level of urgency and business impact of this request**

Does not seem urgent, but did come out of a customer request on dbt slack

Are you interested in contributing to this package?

• [x] Yes, I can do this and open a PR for your review.
• [ ] Possibly, but I'm not quite sure how to do this. I'd be happy to do a live coding session with someone to get this work implemented.
• [ ] No, I'd prefer if someone else did this. I don't have the time and/or don't know how to incorporate the changes necessary.
