3. )

Sorry, i had not looked into the extension since it is not part of core npgsql. As it states: Npgsql.EntityFrameworkCore.PostgreSQL is an Entity Framework Core provider built on top of Npgsql. (and we left npgsql before this extension was started).

I guess it would be easy for them to implement a solution, because that basically means adopting the relevant part from the EF SqlServer implementation. But i fear you’re out of luck with them, as support for table partitioning is still an open issue in their project.

 

Best regards

Wilm.
