The standard answer to this has been to use PL/Tcl for your trigger
function instead of PL/pgSQL. I imagine PL/Python would work also, but
I'm not sure.
(FWIW, PL/R would work too, but I doubt you would want to install R just
to have this capability.)
I looked a bit at making this work in PL/pgSQL at some point -- IIRC the
issues to be solved were non-trivial.
