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!
