-----------
Fix check_sql_fn_retval to allow the case where a SQL function declared to
return void ends with a SELECT, if that SELECT has a single result that is
also of type void. Without this, it's hard to write a void function that
calls another void function. Per gripe from Peter.
Back-patch as far as 8.0.
