Would it bring less confusion if we append something like "When querying
pg_settings"? I can see David's point the current phrasing is
confusing: we don't know if this comes from pg_settings or from SHOW.
It obviously refers to the former, but one can understand that it refers
to the latter.
A second parameter in config.sgml where this formulation is used is
segment_size.
