I proposed a patch at https://postgr.es/m/202409110955.6njbwzm4ocus@alvherre.pgsql FileFallocate failure: errmsg("could not allocate additional %lld bytes from position %lld in file \"%s\": %m", (long long) addbytes, (long long) seekpos, FilePathName(v->mdfd_vfd)), FileZero failure: errmsg("could not zero additional %lld bytes from position %lld file \"%s\": %m", (long long) addbytes, (long long) seekpos, FilePathName(v->mdfd_vfd)), I'm not sure that we need to talk about blocks, given that the underlying syscalls don't work in blocks anyway. IMO we should just report bytes. -- Álvaro Herrera 48°01'N 7°57'E — https://www.EnterpriseDB.com/ "No hay ausente sin culpa ni presente sin disculpa" (Prov. francés)
