Well, if the API is going to be invoked by C UDFs, it could assume that
the environment has been appropriately initialized.

I think it would be possible to provide such an API (although it would
take a considerable amount of work). However, I don't see the point --
why would an application want to use the API? SQL is much more flexible.
