d8b77e20fc Query planner heuristic update:
When doing a full table scan on a table that has an equality constraint on
an unindexed column, do not allow the estimated number of output rows to
be greater than half the total number of rows in the table.

0c4de2d96d A simpler fix for ticket [3a88d85f36704eebe1] - one that uses less code.

a serious problem.
