IIRC the patch only provides the syntax for CURSOR to PL/pgSQL. Not real cursor support on the SPI level.
So it's still the same as before, the backend will try to suck up the entire resultset into the SPI tuple table
(that'smemory) and die if it's huge enough.
What we really need is an improvement to the SPI manager to support cursor (or cursor like behaviour through
repeated executor calls).
