You're passing the wrong parameter value, and probably not declaring it
to be the right type either. CHAROID is not the type you think it is
(BPCHAROID is what you want), and "CStringGetDatum" is not the way to
convert a C string into a char(N) datum. The most bulletproof way
to do the latter is to use DirectFunctionCall3 to invoke bpcharin().
