How to change db you test against?

Background: Running a Spring backend with Postgresql DB (3 envs: local, staging, prod). I'm using IntelliJ.

Problem: My local db is in a bad state and I need to test something that I'm sure would work with good data.

Question: Is there any way I can use my local changes to test against staging? (Don't push to staging branch until I know for sure that this would work)
