Frequently Asked Questions​

Q: How do I upgrade or downgrade to DuckDB version 0.9.2 or other versions?

A: Follow the instructions located here. We recommend direct download of the binary of the desired version rather than using a package manager.

In Python for example, use pip install duckdb==0.9.2 --upgrade.

Q: Why does MotherDuck need to upgrade to 0.9.2?

A: The upgrade is important to enhance the stability and performance of DuckDB. Commonly requested features including Iceberg support are also dependent on version 0.9.2. MotherDuck also must maintain a consistent DuckDB version internally in order to improve the user experience and address support questions as quickly as possible.

Q: Will it happen again?

A: MotherDuck will soon be able to seamlessly support multiple versions of DuckDB.

Q: What happens if I am using a 3rd party tool that’s on a different version of DuckDB than MotherDuck?

A: Currently both MotherDuck and its clients need to be on the same version of DuckDB. If MotherDuck, for example, is on 0.9.2 and a 3rd party tool is on 0.8.1, MotherDuck and the 3rd party tool will not be able to communicate with each other.

Q: What error will I get if I try to connect to MotherDuck with a stale client?
