Log Message:
API change: RV's may not be used more than once within scope of the same
query.  This change is for SQL generation, where each reference to a table
or join thereof must have a unique alias (i.e., a distinct relation
variable).  Also, extended tests for 'keep' and 'rename' to cover outer
joins as well as inner ones.
