Personally, I like the ability to define such at a command line level ...
*especially* as it pertains to pointing to various directories ... I am
against pulling the -X functionality out ... if you don't like it, don't
use it ... add the GUC variable option to the mix, but don't take away
functionality ...

Hell, take a look at what you are saying above: because someone might
forget to set -X, let's get rid of it in favor of a setting in a file that
someone might forget to edit?

Either format has the possibility of an error ... if you are so
incompetent as to make that sort of mistake on a production server, it
won't matter if its a GUC variable, environment variable or commnd line
argument, you will still make that mistake ...
