I have long-running prevent wraparound VACUUM (it has been running for 6 days at the moment). The question is: if I interrupt this process in some way (restart database, for instance), will it start from the beginning? On the one hand, it opens a new transaction at the beginning (according to the source code), on the other hand it updates some data on the disk (WAL?). It confuses me. Could someone please explain me this? - With best regards, Andrey Zhidenkov
