    Parameters:
    
    constraintName - Constraint name.
    
    constraintSchemaName - the schema that constraint lives in.
    
    tableName - Table name.
    
    tableId - UUID of table.
    
    tableSchemaName - the schema that table lives in.
    
    indexAction - IndexConstantAction for constraint (if necessary)
    
    behavior - the drop behavior (e.g. StatementType.DROP_CASCADE)
