I've reviewed this patch. I think this is the feature of high demand.
New columns (stats_since and minmax_stats_since) to the
pg_stat_statements view, enhancing the granularity and precision of
performance monitoring. This addition allows database administrators
to have a clearer understanding of the time intervals for statistics
collection on each statement. Such detailed tracking is invaluable for
performance tuning and identifying bottlenecks in database operations.

I think the design was well-discussed in this thread. Implementation
also looks good to me. I've just slightly revised the commit
messages.

I'd going to push this patchset if no objections.
