[ scratches head ... ] That implies that heap_fill_tuple came to a
different conclusion about a tuple's data size than the immediately
preceding heap_compute_data_size. Which I would sure want to believe
is impossible. Have you checked for flaky memory on this machine?
We are doing so now -- although the RAM is ECC and just a few months
old, so flakiness seems a distant possibility. I will report back
after we've given it a proper thrashing with memtest.
Apparently bad RAM can also mean faulty CPU (bad cache, heat problems,
etc). memtest86 seems ... rough ... at best when it comes to finding
issues; I've had some systems run it for a day yet continuously segfault
in real-world use until the RAM was re-seated or swapped out.
