I think the part of this example that doesn't work is returning from the
function without having exited your SPI context. If you need to produce
multiple rows from a single SPI query, the best solution is to collect
them all during a single call and return them in a tuplestore. You can
*not* return without having called SPI_finish to balance your
SPI_connect.
