At SERIALIZABLE level with v2/v5 I get an error which I don't have before the patch (but no crash):
pgbench: error: client 6 script 0 aborted in command 594 query 0: ERROR:  could not serialize access due to read/write dependencies among transactions
DETAIL:  Reason code: Canceled on identification as a pivot, during conflict out checking.
I should correct myself: the mentioned error under SERIALIZABLE is also present before the patch.
