Since such a process isn't a real backend, pgstat.c gets confused. This accounts for recent reports of strange "invalid server process ID -1" log messages during crash recovery. There isn't any point in attempting to make the report, since we'll discard stats in such scenarios anyhow. regards, tom lane
