Constructor.

Parameters:

constraintName - The constraint name.

constraintSchemaName - The schema that constraint lives in.

characteristics - The (presumably) altered enforcement characteristics.

tableName - Table name.

tableId - The UUID of table.

tableSchemaName - The schema that table lives in.

indexAction - IndexConstantAction for constraint
