AFAIK the only way fcinfo would be null is if PG didn't think that the
function was V1 call convention. I see that you do have the
PG_FUNCTION_INFO_V1 macro in there, which eliminates the most obvious
explanation. Are you sure that the SQL-level CREATE FUNCTION command
references this function name and not some other one?
