I agree with the general idea, but it seems we are accumulating a lot
of provider-specific functions. Should we define a provider struct with
its own methods?

That would be a good step toward making the provider catalog-driven.
Even if we don't support CREATE LOCALE PROVIDER, having space in the
catalog would be a good place to track the provider version.

This seems to be causing a test failure in 020_createdb.pl.

See comments above about v9-0003.
