I think that you mean this one: https://www.postgresql.org/message-id/CAH2-WznCscXnWmnj=STC0aSa7QG+BRedDnZsP=jo_r9guzv...@mail.gmail.com Still that looks entirely different to me. Here we have a problem where the number of free blocks stored may cause an overflow in the internal routine retrieving a free block, but your other thread is about long being not enough on Windows. I surely agree that there's an argument for improving this interface and remove its use of long in the long-term but that would not be backpatched. I also don't see why we cannot do the change proposed here until then, and it's backpatchable. There is a second thread related to logtape.c here, but that's still different: https://www.postgresql.org/message-id/flat/CAH2-Wzn5PCBLUrrds%3DhD439LtWP%2BPD7ekRTd%3D8LdtqJ%2BKO5D1Q%40mail.gmail.com -- Michael
