[Info-ingres] stats on tables with more than 1million rows

Hi All,

It appears that optimizedb automatically switches to sampling once a table breaks 1million rows, which is cool.

But now I have a table with unique keys which the stats insist is a non-unique key with an average count per value of 1.6.

Is this a problem?
