Tom Lane aa27977fe2 Support explicit placement of the temporary-table schema within search_path.
This is needed to allow a security-definer function to set a truly secure
value of search_path.  Without it, a malicious user can use temporary objects
to execute code with the privileges of the security-definer function.  Even
pushing the temp schema to the back of the search path is not quite good
enough, because a function or operator at the back of the path might still
capture control from one nearer the front due to having a more exact datatype
match.  Hence, disable searching the temp schema altogether for functions and
operators.
