Suppress attempts to report dropped tables to the stats collector from a
startup or recovery process. 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 discardstats in such scenarios anyhow.
