1st, i think, you should it rewrite to:

((constraint_checker('manager',manager,null,null) = 'OK'))


2nd, check-constraints ARE NOT DEFERRABLE !!!


http://www.postgresql.org/docs/current/static/sql-createtable.html says:
Currently, only UNIQUE, PRIMARY KEY, EXCLUDE, and REFERENCES (foreign
key) constraints accept this clause. NOT NULL and CHECK constraints are
not deferrable.
