Add an entry to the discussion of regression test failures about the

possibility of a failure due to stack overflow when max_stack_depth is
not set properly for the platform.

+     If the errors test results in a server crash
+     at the select infinite_recurse() command, it means that
+     the platform's limit on process stack size is smaller than the
+      parameter indicates.  This
+     can be fixed by running the postmaster under a higher stack
+     size limit (4MB is recommended with the default value of 
+     max_stack_depth).  If you are unable to do that, an
+     alternative is to reduce the value of max_stack_depth.
