-1, at least for the moment. Sometimes a user doesn't know what they're
looking for coupled with being unaware of what the default value is. If
a setting is set to a default value and that value is the problematic
setting, a user should be able to see that even in a full list.
(The \dt searching only tables "search_path" vs. the database has also
bitten me too. I did ultimately learn about "\dt *.*", but this makes
the user have to unpack more layers to do simple things).
