This thread seems to have wandered away without asking the critical
question "what did you mean by that?"

It's not possible for an index to have more rows than there are in
the table unless something is seriously broken. And there aren't
any SQL operations that let you inspect an index directly anyway.
So: what is the actual observation that led you to the above
conclusion? Facts, please, not inferences.
