Well, that's not really the problem. Your data is corrupted -
increasing the index row size is not going to fix it.
I'm not really knowledgeable enough about the guts of the database to
know whether there are lower-level tools that could be used to rescue
your data. I wonder if you'd have any luck selecting data a few rows
at a time (LIMIT 100, say, without ORDER BY). That might at least
enable you to get some of the data out of there, if there are some
pages that are undamaged. But I'm grasping at straws here.
