      Description

      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.
