Can the error message be more explicit somehow? Otherwise people will be
quite confused as to where no_such_function() is coming from.
<begin creature-feep>
BTW, I'd think this functionality would be valuable for every PL. Maybe
it's worth adding formal support for it to pg_language et all and leave
it up to each language to decide whether it's supported or not? Multiple
init functions might be useful too, similar to how we support multiple
hook functions (though presumably a field of regproc[] is a better way
to handle that...)
I'm also wondering if there'd be value to supporting code that runs on
each function invocation.
