Which one, there seem to be several....
So this seems like it's more likely to be a symptom of whatever is
causing the table to grow than a cause? That is, there's some bug
causing the standby to extend the btree dramatically resulting in lots
of uninitialized pages and touching those pages triggers this bug. But
this doesn't explain why the btree is being extended I don't think.
