I'd imagine that we simply set the context to "$language function
$name", probably in fmgr_info_other_lang(). If a language wants more
than that, it can set another level of context. Of course this way we
would not save much code in, say, PL/Perl, but all the other PLs that
are currently not using this stuff at all would get it for free.
