I am not sure where we are on that based on the objection from Alvaro
to not remove the first column in wait_event_names.txt about
greppability.  Anyway, I am not seeing any objections behind my
suggestion to simplify the second column and remove the quotes from
the event names, either.  Besides, the suggestion of Andres to improve
the error message on parsing and show the line information is
something useful in itself.

Hence, attached is a rebased patch set that separates the work into
more patches:
- 0001 removes the quotes from the second column, improving the
readability of the .txt file.
- 0002 fixes the report from Andres to improve the error message on
parsing.
- 0003 is the rename of the wait events, in preparation for...
- 0004 that removes entirely the first column (enum element names)
from wait_event_names.txt.

I would like to apply 0001 and 0002 to improve the format if there are
no objections.  0003 and 0004 are still here for discussion, as it
does not seem like a consensus has been reached for that yet.  Getting
more opinions would be a good next step for the last two patches, I
assume.

So, any comments?

Subject: [PATCH v2 1/4] Remove quotes from second column of
 wait_event_names.txt

These are not required, as the fields quoted are single words.

Subject: [PATCH v2 2/4] Add information about line contents on parsing failure
 of wait_event_names.txt

The contents of the line whose parsing failed was not reported in the
error message produced by generate-wait_event_types.pl, making it harder
to debug.

Subject: [PATCH v2 3/4] Rename wait events with more consistent camelcase
 style

This will help in the introduction of more simplifications with the
generation of wait event data using wait_event_names.txt.  The event
names used the same case-insensitive characters, hence applying lower()
or upper() to the monitoring queries allows the detection of the same
events as before this change.

Subject: [PATCH v2 4/4] Remove column for enum elements in
 wait_event_names.txt

This file is now made of two columns, removing the column listing the
enum elements for each wait event class:
- Camelcase event name used in pg_stat_activity.  There are now
unquoted.
- Description of the documentation.

The enum elements are generated from what is now the first column.
