Oh, one more thing: the patch also includes a minor cleanup to the
FunctionMode enum, which I discussed with Joe Conway via private
email. The "use a tuple store provided by the function" mechanism is a
bit of a hack right now, but Joe and I discussed making it more
general (adding another FunctionMode for it, and allowing it to be
specified when executing CREATE FUNCTION). That will wait for 7.4,
however.

I also removed some spi.c functions that were just wrappers over the
appropriate "regular" postgres functions (e.g. SPI_pfree), and
replaced them with macros. IMHO that communicates the intent more
clearly.

Cheers,

Neil
