I tried running this in both windows at the same time (this is the inserttest() without the update
statment at the beginning):
begin;
set transaction ISOLATION LEVEL SERIALIZABLE;
select inserttest();
commit;

and I got this error:
ERROR: could not serialize access due to concurrent update
SQL state: 40001
Context: SQL statement "delete from testserial"
PL/pgSQL function "inserttest" line 2 at SQL statement
