Log message:
    - Corrections for tables, columns with uppercase characters
    - Don't attempt to convert partial or expressional unique indexes
    - Don't attempt to convert unique indexes based on a non-default
    opclasses

    - Untested prevention of conversion of non-btree indexes unique
    indexes.  Untested as postgresql doesn't allow hash, gist, or rtree
    based indexes to be unique.
