Please find attached v2 making use of SRF.
v2:
- adds a new pg_wait_event.c that acts as the "template" for the SRF
- generates pg_wait_event_insert.c (through generate-wait_event_types.pl) that
is included into pg_wait_event.c
That way I think it's flexible enough to add more code if needed in the SRF.
The patch also:
- updates the doc
- works with autoconf and meson
- adds a simple test
I'm adding a new CF entry for it.
