pg_upgrade does this in controldata.c for this exact reason:

/*
* Because we test the pg_resetxlog output strings, it has to be in
* English.
*/
if (getenv("LANG"))
lang = pg_strdup(ctx, getenv("LANG"));
#ifndef WIN32
putenv(pg_strdup(ctx, "LANG=C"));
#else
SetEnvironmentVariableA("LANG", "C");
#endif
