Possible typos in the #12.1.1 examples

The following documentation comment has been logged on the website:

Page: https://www.postgresql.org/docs/12/textsearch-intro.html
Description:

SELECT title || ' ' || author || ' ' || abstract || ' ' || body AS
document
FROM messages
WHERE mid = 12;

Seems like here the example missed 'm' as an alias and a dot in the `where`
clause:
... messages m
... m.id = 12;

SELECT m.title || ' ' || m.author || ' ' || m.abstract || ' ' || d.body AS
document
FROM messages m, docs d
WHERE mid = did AND mid = 12;

Possibly, the example missed dots:
... m.id = d.id AND m.id = 12;

Thanks!
