Can you tell more about the workload? What INSERT/UPDATE/DELETE commands do you run? How many concurrent clients? Do
yourun vacuum manually or how often does autovacuum kick in? How long did it take for the problem to appear? What
queriesdid you run to find the corruption, and how often? 

I know it's a big ask, but would it be possible to simplify the test case further, to make it reproduce faster? Ideally
asa self-contained test script with any sensitive data removed.
