In response to Bruce's recent question, and remembering the recent
scolding received about removing a "LEFT" from an unrelated patch :),
here's a patch that does that and nothing more: removes all
unnecessary left joins from psql. Done in the theory that we often
point people to psql -E, so our queries there should be as correct
as possible: if the joining column is not null, then we don't need
a left join.
