11 : * NOTES
12 : *
13 : * To make pgstat_report_wait_start() and pgstat_report_wait_end() as
14 : * lightweight as possible, they do not check if shared memory (MyProc
15 : * specifically, where the wait event is stored) is already available. Instead
16 : * we initially set my_wait_event_info to a process local variable, which then
17 : * is redirected to shared memory using pgstat_set_wait_event_storage(). For
18 : * the same reason pgstat_track_activities is not checked - the check adds
19 : * more work than it saves.
