Hi,

Hm, that's pretty awkward. Perhaps we can have a better API for
everything but guc.c?

Or alternatively, perhaps we can just make pg_clean_ascii() return NULL
if allocation failed and then guc_strdup() the result in guc.c?

If we end up needing a two phase approach, why use the same function for
both phases? That seems quite awkward.
