Computation of a recursive common table expression aborts and an error is generated if the computation fails to complete within the specified number of iterations. Recursive subqueries often geometrically increase the amount of resources required for each additional iteration. Set this option to limit the amount of time and resources that are consumed before infinite recursion is detected, yet permit your recursive common table expressions to work as intended.
Setting this option to 0 disables recursive common table expressions.
