Something like this syntax?: JOIN WITH (correlation_factor=0.3) Where 1.0 might mean that for each value on the left there was only one distinct value on the right, and 0.0 would mean that they were entirely independent? (Just as an off-the-cuff example -- I'm not at all sure that this makes sense, let alone is the best thing to specify. I'm trying to get at *syntax* here, not particular knobs.) -Kevin -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
