This is a shortcut for those that are not using the label field. It can
become very verbose always calling Quad with an empty string as the last
parameter.

subject, predicate, object and labels are not indexed, thus, using a where clause on these fields for the DELETE statement does a full-table scan. Using *_hash columns instead will use the indexes.

It appears that preparing an INSERT statement on PostgreSQL actually makes it expecting to receive INSERTs and thus, it create some kind of locks for it. If instead, you only send him DELETE statements, it will indefinitely wait for an INSERT and will hung.

Fix NPE in SQL Quadstore

When `tx.Exec` fails and an error is returned, result is nil. Thus, `result.RowsAffected()` panics.
* Add a missing return statement in the error test.
* Add a second missing return statement just below to return the proper error message if we can't execute `RowsAffected` instead of saying that the triple doesn't exist.

consistent 'route' metaphor, and moved all AND(iterator, iterator)
stanzas out into a single join() function that is more descriptive of
