The issue

Npgsql has a dependency on Microsoft.Extensions.Logging which brings in a dependency on Microsoft.Extensions.DependencyInjection.Abstractions (who knows why...)

These dependencies may be undesirable to upstream consumers and will cause versioning problems with diamond dependencies further down line.

Instead, Npgsql should follow the dependency inversion principal and define it's own logging contract that consumers can adapt to their needs.

Further technical details

Npgsql version: 3.2.0
