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. -- Michael
