I have found a way to write the test case for this patch. This is based on the idea we used in stats.sql. As of now, I have kept the test as a separate patch. We can decide to commit the test part separately as it is slightly timing dependent but OTOH as it is based on existing logic in stats.sql so there shouldn't be much problem. I have not changed anything apart from the test patch in this version. Note that the first patch is just a debugging kind of tool to test the patch. Thoughts? -- With Regards, Amit Kapila.
