Hello.
> Probably, patch in this thread should fix this in btree_xlog_split() too?
I have spent some time trying to find any possible race condition
between btree_xlog_split and _bt_walk_left… But I can’t find any.
Also, I have tried to cause any issue by putting pg_sleep put into
btree_xlog_split (between releasing and taking of locks) but without
any luck.
I agree it is better to keep the same locking logic for primary and
standby in general. But it is a possible scope of another patch.
Thanks,
Michail.
