I note Tom made some changes to this patch after it went in. For the record, it was always my intention that samplecount count the number of _tuples_ returned while sampling, rather than the number of _iterations_. I'll admit the comment in the header was wrong. While my original patch had a small error in the case of multiple tuples returned, it would've been correctable by counting the actual number of sample. The way it is now, it will show a bias if the number of tuples returned increases after the first sampled 50 tuples. However, my knowledge of statistics isn't good enough to determine if this is an actual problem or not, since the way it is now will sample more initialially...
