Thank you for your attention.

Thanks, I'll look into this. The fix seems fine at a quick glance, but I'll think about the performance aspect a bit more.
I apologize for the mistake in my patch: "if GinPageIsIncompleteSplit(page)" is
missing a parenthesis, it should be "if (GinPageIsIncompleteSplit(page))"

Another way to create a scenario with incomplete splits, which doesn't involve any crashes or errors, would be to perform PITR to just between the insert and the finish-split records. But the fault-injection seems easier.
I agree it, fault-injection is easier than PITR.
