Hi,

On http://www.postgresql.org/docs/9.1/interactive/runtime-config-resource.html#RUNTIME-CONFIG-RESOURCE-MEMORY
max_stack_depth's default setting was wrote it is two megabytes. But,I think that this explanation is not true.
In my environment, When "`ulimit -s` - 512KB" value is less than 2MB, this value is set up as a default value.
And I also notice that If "ulimit -s" value is "unlimited", then "100KB" is set up on the PostgreSQL 9.0 and less.
So,I think that you should write that max_stack_depth's default setting depends on stack size when it is less than 2.5MB,
and "100KB" is set up on the PostgreSQL 9.0 and less when stack size is unlimited.

Regards.
