FYI I think I've reproduced the issue (with a different script), I've
started a thread on pgsql-hackers:

https://www.postgresql.org/message-id/de52b282-1166-1180-45a2-8d8917ca74c6%40enterprisedb.com

Obviously, I can't be sure it's exactly the same issue, but the symptoms
seem to match what Depesz reported (gaps in data etc.). I don't know
what the root cause is, or fix. But there's more info (and scripts) in
the hackers thread.
