Liquibase add-foreign-key-constraint deferrable: what does it mean? -

Looking for docks for liquids and a property is called deferrable. But docs do not really mention that what does the property do anybody know?

exceptionally
not insufficient < Br> It controls whether the barrier can be postponed or not. An obstacle which is not deferrable will be checked immediately after every command Checking the obstacles to be postponed can be postponed until the end of the transaction (using the set constraints command) is not the final defining only foreign key constraints currently this section All other obstacle types are not suspended.

In short, assume two tables that have cyclical FK dependence. When we insert for data, the reference table is not present in both the tables and the FK barriers, then it is not postponed, throwing the DB will be a violation of the FK constraint. If suspended, verification will be done at the time of transaction.
