https://www.postgresql.org/message-id/attachment/49977/0001-Logical-replication-support-for-initial-data-copy-v6.patch
logical replication now seems pretty stable, at least for the limited
testcase that I am using. I've done dozens of pgbench_derail2.sh runs
without failure. I am now changing the pgbench-test to larger scale
(pgbench -is) and longer periods (-T) which makes running the test slow
(both instances are running on a modest desktop with a single 7200
disk). It is quite a bit slower than I expected (a 5-minute pgbench
scale 5, with 8 clients, takes, after it has finished on master, another
2-3 minutes to get synced on the replica). I suppose it's just a
hardware limitation. I set max_sync_workers_per_subscription to 6 (from
default 2) but it doesn't help much (at all).
To be continued...
Thanks,
Erik Rijkers
