Hi, can I realize a running mean filter using window functions?
What I can think of is: SELECT avg(random) OVER (PARTITION BY floor(time_s / 60) ORDER BY floor(time_s / 60)) FROM ( SELECT generate_series(0,600,20) time_s, random() ) as data; which averages all measurements in one minute, but not every line with its following two lines. Any suggestions?
