Thanks for that snippet. why is that 'STABLE' at the end of the function ?
i am stuck at createlang for plpythonu! with postgres user
error reads:
$createlang plpythonu template1;
createlang: language installation failed: ERROR: could not load library
"/usr/local/pgsql/lib/plpython.so": /usr/local/pgsql/lib/plpython.so: undefined
symbol: Py_InitModule4_64
i am on a x86_64 linux box. couldnt comprehend the error.
plpython.so is in /usr/local/pgsql/lib
whats wrong?

KM
