The two-arg form of the current_setting() function will allow a
fallback value to be returned instead of throwing an error when an
unknown GUC is provided.  This would come in most useful when using
custom GUCs; e.g.:

There already _is_ a two-argument form of current_setting() that yours
somewhat conflicts with:

  current_setting(setting_name [, missing_ok ])

Apologies; I have no idea how this email got re-sent, but it is quite old and a mistake.
