Add system view pg_wait_events
This new view, wrapped around a SRF, shows some information known about
wait events, as of:
- Name.
- Type (Activity, I/O, Extension, etc.).
- Description.
All the information retrieved comes from wait_event_names.txt, and the
description is the same as the documentation with filters applied to
remove any XML markups. This view is useful when joined with
pg_stat_activity to get the description of a wait event reported.
Custom wait events for extensions are included in the view.
Original idea by Yves Colin.
