Thank you for your comment. Sorry for being late. > SELECT FOR UPDATE SKIP LOCKED might skip a large number of rows, > leading to > a high volume of log messages from log_lock_failure in your current > patch. > Could this be considered unintended behavior? Would it be better to limit > the number of log messages per query? It is necessary to suppress the generation of a large amount of logs due to SKIP LOCKED. But I think that when using SKIP LOCKED, the locks are often intentionally bypassed. It seems unnatural to log only the first write or to set a specific number of samples. What do you think if we simply don't log anything for SKIP LOCKED? Regards,
