## Additional details

Please add 1-line descriptions for the `force_delete_table_data_entry` and `change_function_privilege` events. This will bring them in line with the other events documented on this page, which have descriptions.

* https://www.cockroachlabs.com/docs/stable/eventlog.html#force_delete_table_data_entry
* https://www.cockroachlabs.com/docs/stable/eventlog.html#change_function_privilege

In addition, some events have 1-line descriptions that convey no new information beyond the event name, which is already shown. For example:

* captured_index_usage_stats
* hot_ranges_stats
