NpgsqlCommandBuilder doesn't implement any interface.

You may need to create some adaptor which can use a custom common
interface. This way you would have adapters for each provider you want
to use.

Hmmm, while working with commandbuilder and dataadapter, you don't need
to specify manually the insert command. NpgsqlCommandBuider can do that
for you automatically.

I hope it helps.
