Dear Michael, Chris and Tom,

I understand your arguments and its utility.

I found that this strange error appears after making
temporary tables.
test=> CREATE TEMPORARY TABLE temp (id int);
CREATE TABLE
test=> CREATE EXTENSION file_fdw WITH SCHEMA pg_temp_3;
ERROR: function file_fdw_handler() does not exist
I would try to understand this problem for community and
my experience.
