Pathname GUCs can have spaces in them (that's even pretty common, on
certain platforms). Other GUCs contain SQL identifiers, which can
legally have spaces in them too. So really this is a mechanism
deficiency, not something we should work around by instituting a policy
against spaces in GUC values.
