As discussed upthread, I have added documentation for all the possible wait events and an example. Some of the LWLocks like AsyncQueueLock and AsyncCtlLock are used for quite similar purpose, so I have kept there explanation as same.
Do you think it worth grouping rows in "wait_event Description" table by wait event type?
They are already grouped (implicitly), do you mean to say that we should add wait event type name as well in that table? If yes, then the only slight worry is that there will lot of repetition in wait_event_type column, otherwise it is okay.
