Hi Alvaro, Do you mean this to be a bug? My question is in my error log I'm getting query text for that corresponding "could not serialize access due to concurrent update" error failures. But can I get the other transaction which committed and which is responsible for this above serialization update? Looking forward to hear from you!.
