That wasn't quite my question. I'm familiar with the row-level locking and the locking messages in general, but this
messageimplies there is such a thing as an AccessExclusiveLock on a tuple, which is new to me. I wasn't able to
producethis message experimentally doing various combinations of UPDATE statements and SELECT FOR UPDATEs, or even with
explicitLOCK ACCESS EXCLUSIVE MODE, thus the question.
