Indeed.  The failure suggests that you tried to modify the structure of
pg_index rows and didn't get all the consequences right ... but what you
said does not offer any reason to change pg_index.

There's already some things in CVS HEAD about allowing plugins to
manufacture hypothetical indexes for the planner to consider --- have
you looked at that?
