I bet he's using the temp table without EXECUTE. That would've failed even without the other "calling"
function around it, as soon as he uses it more than once per session.
SPI still needs to learn how to determine if a query uses temp tables somewhere in order to silently
re-preparequeries when required. And I am absolutely sure this is not an issue we should address in PL/pgSQL. It
hasto be solved on the SPI level.
