Re: SPI_ERROR_UNCONNECTED in python callback function

What this probably means is that plpython is failing to use
SPI_push/SPI_pop properly --- these should be called around
any operation that might invoke an independent SPI-using function:
http://www.postgresql.org/docs/8.3/static/spi-spi-push.html

I'm not enough of a plpython user to be excited about trying to fix it,
but if you are then please send a patch.
