This has come up before.  We could show the string value of the GUC, if
it's been set in postgresql.conf, but we do not have correct values for
any of the other columns in pg_settings; nor are we even sure that the
module will think the value is valid once it does get loaded.  So the
consensus has been that allowing the GUC to be printed would be more
misleading than helpful.
