Subject: Suggestion on Document for Version 12 Section 40.3
Date: Thu, 09 Jan 2020 08:28:05 +0000
Message-ID: <[email protected]> (raw)
The following documentation comment has been logged on the website:
Page: https://www.postgresql.org/docs/12/rules-materializedviews.html
Description:
Hello all,
I'm reading Section 40.3, and there is an example (the third square by
reverse order):
SELECT word FROM words ORDER BY word <-> 'caterpiler' LIMIT 10;
word
---------------
cater
caterpillar
Caterpillar
caterpillars
caterpillar's
Caterpillar's
caterer
caterer's
caters
catered
(10 rows)
As shown here https://www.postgresql.org/docs/current/pgtrgm.html, the
operator `<->` is in an additional module. Without the context, the reader
will need searching to help understand the meaning. It would be better if
further reference is given.
