pg_migrator requies tables using tsvector data types to be rebuilt, and
there has been discussion of how to prevent people from accessing those
columns before they are rebuilt. We discussed renaming the tables
(affects all columns) or columns, using rules (not fine-grained enough),
or using column permissions (doesn't affect super-users).
My new idea is to mark the column as "dropped" and unmark them before
rebuilding the table. That might be the best I can do. Comments?
