Best guess:
CREATE TEMP TABLE ... ON COMMIT DROP AS
or
DROP TABLE IF EXISTS ..
You show a lot of detail in the function but its not useful. Given the
stated problem your queries or "SELECT '1'::text" both will exhibit the
same behavior. What you don't show or describe, however, is how and when
the function is called.
