That would be pretty cool to get that done in an automated way, I've
wanted that for a few years now. And I guess that a few others have
the same feeling after missing to update these docs when adding a new
wait event, or just to enforce this alphabetically, so let's do
something about it in v17.
Thanks for the feedback!
About the alphabetical order, could we have the script enforce a sort
of the elements parsed from waiteventnames.txt, based on the second
column? This now relies on the order of the items in the file, but
my history with this stuff has proved that forcing an ordering rule
would be a very good thing long-term.
Not having the lines in order would not have been a problem for the perl script
(as it populated the hash table based on the category column while reading the
text file).
That said I do agree that enforcing an order is a good idea, as it's "easier"
to read
the generated output files (their content is now somehow "ordered").
This is done in V3 attached.
Seeing waiteventnames.txt, I think that we should have something
closer to errcodes.txt. Well, seeing the patch, I assume that this is
inspired by errcodes.txt, but this new file should be able to do more
IMO:
- Supporting the parsing of comments, by ignoring them in
generate-waiteventnames.pl.
- Ignore empty likes.
- Add a proper header, copyright, the output generated from it, etc.
- Document the format lines of the file.
Fully agree, it's done in V3 attached.
It is clear that the format of the file is:
- category
- C symbol in enums.
- Format in the system views.
- Description in the docs.
Or perhaps it would be better to divide this file by sections (like
errcodes.txt) for each category so as we eliminate entirely the first
column?
Yeah, that could be an option. V3 is still using the category as the first
column
but I'm ok to change it by a section if you prefer (though I don't really see
the need).
Perhaps waiteventnames.c should be named pgstat_wait_event.c?
Agree, done.
Similarly,
wait_event_types.h would be a better name for the set of enums?
Also agree, done.
utils/adt/jsonpath_scan.c \
+ utils/activity/waiteventnames.c \
+ utils/activity/waiteventnames.h \
+ utils/adt/jsonpath_scan.c \
Looks like a copy-pasto.
Why do you think so? both files have to be removed.

Subject: [PATCH v3] Generating wait_event_types.h, pgstat_wait_event.c and
waiteventnames.sgml
Purpose is to auto-generate those files based on the newly created
waiteventnames.txt file.
Having auto generated files would help to avoid:
- wait event without description like observed in
https://www.postgresql.org/message-id/CA%2BhUKGJixAHc860Ej9Qzd_z96Z6aoajAgJ18bYfV3Lfn6t9%3D%2BQ%40mail.gmail.com
- orphaned wait event like observed in
