Dropping and recreating the index would probably make the message go
away. We've been puzzling over sporadic reports of this notice for
some time now (check the pghackers archives). If you can come up with
a reproducible way of getting into this state, we'd love to see it.
We know how to create a situation where there are fewer index than
heap tuples --- and that's harmless, at least for the known way of
causing it. But we've got no idea how there could be more index than
heap entries.
