Temp tables live in a schema that is effectively inserted into your
search path ahead of whatever schema(s) are explicitly listed there.
For instance, suppose
CREATE SCHEMA a;
SET search_path = a, public;
CREATE TABLE t1 (...);
-- t1 is created in schema a
SELECT * FROM t1;
-- same as SELECT * FROM a.t1;
Now if I do
CREATE TEMP TABLE t1 (...);
then SELECT * FROM t1 will reference the temp table ... but I can still
get to the permanent table by explicitly qualifying it as "a.t1".

You drop the temp table.

Only if you do it twice --- after the initial DROP, the permanent table
would come back "into view".
