Обсуждение: valid using INITIALLY DEFERRED

Hello,

  I try INITIALLY DEFERRED clause. In doc is relation between general
constraint and this clause. But combination with CHECK clause ends with
err message misplaced INITIALLY DEFERRED clause.

Is possible use INITIALLY DEFERRED with other variants constraint than
REFERENCES?

Thank You

The CREATE TABLE documentation for INITIALLY DEFERRED says, "If a
constraint is deferrable, this clause specifies the default time
to check the constraint."  Just above that, the documentation for
DEFERRABLE says, "Only foreign key constraints currently accept
this clause.  All other constraint types are not deferrable."

No, we only support deferring foreign key constraints at the moment.
