Well, we are already inconsistent about this. PL languages and index
access methods, for example, don't have schema-ified names.

This is isomorphic to the argument about whether default_text_search_config
is a good idea; indeed, I think that default_text_search_config pretty
much solves this problem already, for the places where it's sane to have
the configuration-in-use depend upon context. The problem with using
schemas for TS configs is that we can't prevent the search result from
changing in contexts where it mustn't change. At least, not short of
requiring fully-qualified config names in those places, which doesn't
sound like an advance in usability.
