Marc-André Bombeck 090e3d9a7e perf(measurements): weigh pulse days with window functions over one scan ...

The day weight joined its source to an hour grouping of itself. With
stale or missing planner statistics, as after a new account imports a
year of pulse below the autoanalyze threshold, the planner ran that
join as a nested loop and the all-time pulse aggregate ran into the
60 s statement timeout. The weight is now two window passes over one
scan: the readings in a row's hour, and one marker per hour summed over
the day for the hour count. The weights are unchanged.

A new integration test seeds over 100k pulse rows with autovacuum off
and no ANALYZE, bounds the all-time reader and a zoned per-source mean
well under the timeout, and compares every row's weight against the
earlier self-join after ANALYZE. The ANALYZE the metric-series snapshot
test needed for the same trap is gone.
