I want to override structure\_dump in the MysqlAdapter class. (It  
doesn’t dump some stuff I need for my implementation and I’m extending  
it to do that.)

I know how to override methods in application code.  
MysqlAdapter#structure\_dump is called from the rake task  
db:structure:dump, and I can’t figure out where to put the overriding  
implementation so that it gets called when the rake task is invoked.  
What’s the secret?
