I think you're probably shooting yourself in the foot here:

            /* pfree() the memory allocated for the previous candidate. FIXME: Avoid
            * meddling with the internals of a StringInfo, and try to use an API.
            */
            if( cols.len > 0 )
            {
                pfree( cols.data );
                cols.data = NULL;
            } /*IF col.len>0*/

Don't do that, use resetStringInfo() instead.
