Hi,
Statistics collector has been removed since 5891c7a8ed8f2d3d5, but there
was a comment referring 'statistics collector' in pg_statistic.h.
> Note that since the arrays are variable-size, K may be chosen by the
> statistics collector.
Should it be modified to 'cumulative statistics system' like manual on
monitoring stats[1]?
Its title has changed from 'statistics collector' to 'cumulative
statistics system'.
