Telerik,
This is a feature request to add the ability to override a connection itself and not just the connection string.
The motivation behind this is for IAM based authentication, where usernames and passwords are no longer used but usernames and short lived tokens are.
Many database providers provide a Factory or Builder to allow a Connect to be built that allows the password to be requested when needed. In the case of Postgres, this is the NpgsqlDataSourceBuilder class.
I'm not sure what the contract would look like to achieve this, but setting the connection itself, one way, shape, or form, is greatly needed.
Thanks,
Shawn
