A bigger risk is that something might elog(ERROR) while you have the
"wrong" locale set, denying you the chance to put back the right one.
I think this code is not nearly paranoid enough about how much it does
while the wrong locale is set.

I'd go so far as to make it a critical section --- that ensures that any
ERROR will be turned to FATAL, even if it's in a subroutine you call.
