This patch looks good to me. It's a very nice simplification of the
initdb.c code, even without the new feature.

I found that the addition of

#include <ctype.h>

didn't appear to be necessary. Maybe it was required before
guc_value_requires_quotes() was changed?

I would remove the

#if DEF_PGPORT != 5432

This was in the previous code too, but now if we remove it, then we
don't have any more hardcoded 5432 left, which seems like a nice
improvement in cleanliness.
