I hope I'm not writing wrong question to the wrong mailing-list. 
Let me know if I'm. 

I would like to ask when the table reference e.g ( 1234::table1 ) 
return from the SELECT statment. 
e.g. 
> select col1 from table2 
> col1
>---------
> 1234

col1 type is now from ( SET?? not sure) table1 converted to oid by seteval 
and is there a function can converted this to text or int to preform 
calculation? 
Thanks 
Alex
