It means the pgstats subprocess fell far enough behind to drop some
data. This is the designed behavior under heavy load, so it doesn't
bother me particularly. I think the worst known consequence is bogus
entries in pg_stat_activity (eg, if the stats process missed a
backend-exiting message, it would continue to show that backend as
present in pg_stat_activity, until some other backend starts in the
same BackendId slot).
