If multiple interpreters are used, is the single perl_locale_obj

So in other words plperl and plperlu both used in the same query? I
don't see how we could get from one to the other without going through
the outer "postgres" locale first. Or are you thinking something else?
I think you got that it backwards. 'perl_locale_obj' is set to the perl
interpreter's locale, whenever we are *outside* the interpreter.
This crashes with the patch:
postgres=# DO LANGUAGE plperlu
$function$
use POSIX qw(setlocale LC_NUMERIC);
use locale;
setlocale LC_NUMERIC, "sv_SE.utf8";
$function$;
DO
postgres=# do language plperl $$ $$;
server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
The connection to the server was lost. Attempting reset: Failed.
I was going to test using plperl and plperl in the same session and
expected the interpreters to mix up the locales they use. Maybe the
crash is because of something like that, although I didn't expect a
crash, just weird confusion on which locale is used.
