Description Steven Rostedt 2022-09-01 21:48:10 UTC 
The cast function of sqlhist does not implement .buckets as it does for log2.

That is, one could do:

  sqlhist -e 'select comm,prio,cast(delta as log2) from wakeup_lat'

But not:

  sqlhist -e 'select comm,prio,cast(delta as buckets=10) from wakeup_lat'
