I think we can remove the newly added test from the patch and instead combine the 0001 and 0002 patches. I think we should leave the 022_twophase_cascade as it is because it can impact code coverage, especially the below part of the test: # 2PC PREPARE with a nested ROLLBACK TO SAVEPOINT $node_A->safe_psql( 'postgres', " BEGIN; INSERT INTO test_tab VALUES (9999, 'foobar'); SAVEPOINT sp_inner; INSERT INTO test_tab SELECT i, md5(i::text) FROM generate_series(3, 5000) s(i); Here, we will stream first time after the subtransaction, so can impact the below part of the code in ReorderBufferStreamTXN: if (txn->snapshot_now == NULL) { ... dlist_foreach(subxact_i, &txn->subtxns) { ReorderBufferTXN *subtxn; subtxn = dlist_container(ReorderBufferTXN, node, subxact_i.cur); ReorderBufferTransferSnapToParent(txn, subtxn); } ... -- With Regards, Amit Kapila.
