Fdo Postgis Autogenated identity property is mandatory

[bscott]

With FDO it is possible to create a column with Primary = true and autogenerate = false. I think the PostGis provider should not do that assumption and let the user manage the primary key if the autogenerate flag is set to false.

Actually it is mandatory there is the piece of code where you can find the limitation:

void SchemaDescription::DescribeSchema(Connection* conn, FdoString* schemaName) 
{ 
  ... 
        ////////////////// SET AUTO-GENERATED TO SINGLE COLUMN PK OF 
 INTEGRAL TYPE ////////////////// 
  
// TODO: It is possible, that user connects to a datastore that was not created 
// with FDO, using ApplySchema command, so single column PRIMARY  KEY 
// of integral type, may not have associated sequence named according scheme: 
// <tablename>_<columnname>_seq 
// The PostGIS provider uses such scheme to bind a sequence to PK column. 
   
// TODO: In future, it would be a good idea to automatically 
// replace PK of integral type with serial data type, in ApplySchema command. 
     FdoPtr<FdoDataPropertyDefinitionCollection> propsIdentity;   
     propsIdentity = featClass->GetIdentityProperties();  
     if (1 == propsIdentity->GetCount()) 
     { 
       FdoPtr<FdoDataPropertyDefinition> propId = propsIdentity->GetItem(0);  
       assert(NULL != propId); 
   
       if (FdoDataType_Int16 == propId->GetDataType()   
        || FdoDataType_Int32 == propId->GetDataType() 
        || FdoDataType_Int64 == propId->GetDataType()) 
       { 
         propId->SetIsAutoGenerated(true); 
       } 
     }
