IntelliJ is decent and has drivers for pretty much all database systems. It can be downloaded has a stand-alone too (DataGrip)

That is for IntelliJ Ultimate if I am not mistaken: https://www.jetbrains.com/help/idea/connecting-to-a-database... Otherwise as you mention DataGrip https://www.jetbrains.com/datagrip/ seems to be really sleek.

Thank you for the insight!
