An in-core GUC to control the list of indexes that should be allowed
or disallowed is I think asking for trouble, adding schema-related
knowledge directly into the GUC machinery. This does not scale well,
even if you force all the entries to be specified down to the database
and the schema. And it makes harder to control what a "good" behavior
should be at query-level.
