Is int8 a passed-by-value data type on 64-bit platforms? How do we arrange for
that to be the case? I don't see any magic in pg_type.h but I'm not sure what
I'm looking for.

I'm asking because I have another 8-byte data type I want to use and it would
be nice to have that same property, assuming we have it for int8.

Not AFAIK. It would involve fiddeling the catalog, tricky since the
catalog genration script doesn't understand #ifdef's. Also you would
have to add conditionals for the the PG_RETURN_* and PG_GET* macros.

Yes that'd be nice, but not entirely straightforward.

Have a nice day,
