There is second version of patch. I made following changes:

- fix problem with assertion
- use boot_val instead default_val for all configuration data types
- add GUC_JUST_RELOAD status to track what is in configuration file or not
- revert only commented out variables
- add message what is revert to boot value

Joachim, could you explain me second point? I cannot determine
described problem. By my opinion my patch does not change this behavior.
