Hello all, I posted this (see below) Friday to the interfaces list with no response. Does anyone know if what I'm trying to do is possible, or should I just write the entire thing in a C function trigger? The latter would be unfortunate because I think it would be nice to be able to extend PLpgSQL using C functions like this. Anyway, any help or advice will be much appreciated!
