This patch doesn't seem to cope with cases where the supplied tuple has
the wrong number of columns, and it doesn't look like it's being careful
about dropped columns either. Also, that's a mighty bizarre-looking
choice of cache memory context in coerce_to_tuple ... but then again,
why are you bothering with a cache at all for temporary arrays?
