Yes, at the moment they are the wrong way round because of a misinterpretation on my part. Easily fixed, by changing
theSQL part so that the Java code reads: 

...

+ ((primaryTable != null) ? "AND c.relname='" + primaryTable + "' " : "")
+ ((foreignTable != null) ? "AND c2.relname='" + foreignTable + "' " : "")

...

I've attached a patch for this for now. But maybe case-sensitive stuff needs to be resolved?

Thanks,
Jason Davies
