Equally interesting would be:
How many duplicate keys do I have?
An interesting database option might be:
For any foreign key, if there is no existing inversion entry index then
build one.
Another interesting database option might be:
Check the system catalogs for duplicate indexes and remove them if there
are any two completely identical (in columns, asc/desc and type).

PostgreSQL is clearly not the only database with this important need.
