That applies only to the VACUUM chapter. VACUUM and AUTOVACUUM are
controlled by a lot of parameters. Therefor the current documentation
concerning the two mechanism spreads the description across different
pages (20.4, 25.1, VACUUM command). Because of the structure of our
documentation that's ok. But we should have a summary page somewhere -
not necessarily in the tutorial.
There is probably room for improvement, but the section numbers you
mention are not about VACUUM, AFAICT, so I can't really comment on
what you have in mind.
Because of the additional chapter for the 'tutorial' on my local
computer, the numbers increased for me. The regular chapter numbers are
19.4 and 24.1. Sorry for the confusion. In detail:
19.4: parameters to configure the server, especially five parameters
'vacuum_cost_xxx'.
19.10: parameters to configure autovacuum.
19.11: parameters to configure client connections, especially five
parameters 'vacuum_xxx' concerning their freeze-behavior.
24.1: explains the general necessity of (auto)vacuum and their strategies.
The page about the SQL command VACUUM explains the different options
(FULL, FREEZE, ..) and their meaning.
