Subject Rename a key through write to a system table
Author Josef KokeŇ°

I realize that the official answer to "can I rename an index" is "no",
and that directly writing to the system tables is generally a poor idea.
But still: How much damage can I cause by UPDATE on RDB$INDEX_NAME in
RDB$INDICES and RDB$INDEX_SEGMENTS? I have this itch I would like to
scratch, where I created a primary key of a table with a bad name...
