It is?
regression=# create temp table a (x int primary key);
NOTICE: CREATE TABLE / PRIMARY KEY will create implicit index 'a_pkey' for table 'a'
CREATE TABLE
regression=# create table b (y int references a(x));
NOTICE: CREATE TABLE will create implicit trigger(s) for FOREIGN KEY check(s)
ERROR: ALTER TABLE / ADD CONSTRAINT: Unable to reference temporary table from permanent table constraint
Now I realize that this existing special-case argues against the
position I'm taking. But let's argue from actual facts, not
