Aren't heap and index requests supposed to go through the shared buffers anyway?

I suspect you're not tracking what you think you're tracking, which is
why I brought up shared_buffers.
~14k * 8192 (page size) = ~110MB
What it sounds like you're actually tracking are shared buffer requests
and not heap or index requests.
Now, perhaps the test you're running only touched 110MB of the 6G
database, but that seems pretty unlikely.
Thanks,
