Here's an example for you...

begin;

create schema foo;
set search_path to foo;

create table haspk (a int primary key);
create table missingpk (a int);

select relname
from pg_class c
join pg_namespace n on c.relnamespace = n.oid
where nspname = 'foo'
and relkind = 'r'
and c.oid not in (
select conrelid
from pg_constraint
where contype = 'p'
);

abort;
