> A recent change added plan node cardinality to the DESCRIBE output using a "metric" format: 123.46M instead of 123456789. This makes the output easier to read. Also, since all numbers are estimate, having seven or eight digits of precision is not very helpful.
> This ticket requests that the same formatting be used for the other places where the DESCRIBE output shows row counts: table stats, extrapolated row count, partition row counts, and so on.
