I was able to reproduce this random failure and found the following reason:
The Minimum recovery ending location 0/5000000 was more than the
recovery_target_lsn specified is "0/4001198". In few random cases the
standby applies a few more WAL records after the replication slot is
created; this leads to minimum recovery ending location being greater
than the recovery_target_lsn because of which the server will fail
with:
FATAL: requested recovery stop point is before consistent recovery point
I have fixed it by pausing the replay in the standby server before the
replication slots get created.
The attached v29-0002-Keep-standby-server-s-minimum-recovery-point-les.patch
patch has the changes for the same.
Thoughts?
