Previously, pg_newlocale_from_collation() returned NULL as a special case for the DEFAULT_COLLATION_OID if the provider was libc. In that case the behavior would depend on the last call to setlocale(). Now, consistent with the other providers, it will return a pointer to default_locale, which is not dependent on setlocale(). Note: for the C and POSIX locales, the locale_t structure within the pg_locale_t will still be zero, because those locales are implemented with internal logic and do not use libc at all. lc_collate_is_c() and lc_ctype_is_c() still depend on setlocale() to determine the current locale, which will be removed in a subsequent commit.
