Re: C trigger problem : conversion of CString to Datum

Well, CStringGetDatum would be the proper thing to use if you meant to
produce a Datum of type "cstring".  But what you need here is a Datum
of the same type as the target column, which evidently isn't cstring.
Most likely you need to convert the string to type text.
