   The problem appears to be the use of `requiredList` in the definition:
   
   ```
   type ConstraintInfo struct {
        ConstraintName        *string                 
`json:"constraint_name,omitempty"`
        ConstraintType        string                  `json:"constraint_type"`
        ConstraintColumnNames requiredList[string]    
`json:"constraint_column_names"`
        ConstraintColumnUsage []ConstraintColumnUsage 
`json:"constraint_column_usage,omitempty"`
   }
   ```
   
   If I change it to a string array:
   
   ```
   type ConstraintInfo struct {
        ConstraintName        *string                 
`json:"constraint_name,omitempty"`
        ConstraintType        string                  `json:"constraint_type"`
        ConstraintColumnNames []string                
`json:"constraint_column_names"`
        ConstraintColumnUsage []ConstraintColumnUsage 
`json:"constraint_column_usage,omitempty"`
   }
   ```
   
   then I get the expected results:

   but I'm not sure the ramifications of this.
