And also related to the patch trying to improve OOM handling in
pg_locale.c, the point being that elog() cannot be called as long as
the saved locales are not put back in place. The cleanest fix here
would be to use a goto to take the code past restoring the saved
locales, and then issue and ERROR. I think that it would be better to
hit those two stones at once on the other thread.

For the calls in fe-connect.c, why are the calls of
pg_get_encoding_from_locale() requesting to print a message on error?
Shouldn't the caller request to *not* print an error instead and then
store an error string in conn->errorMessage if the encoding is < 0? It
seems to me that at the end the right call is to just remove
write_message all together and let the caller decide the error message
it wants. For HEAD that would be a fine cleanup to do. A patch does
not look that complicated, I could get one out according to those
