pg_regress.c and Utils.pm force LC_MESSAGES to C, explaining
* Set translation-related settings to English; otherwise psql will
* produce translated messages and produce diffs.
While that seems clearly necessary, I'm inclined to think that we
should not mess with the user's LC_XXX environment more than we
absolutely must. pg_regress only resets the rest of that if you
say --no-locale, an option the TAP infrastructure lacks.
In short, I think the committed fix is better than this proposal.
