Re: gsoc, store hash index tuple with hash code only - Mailing list pgsql-hackers

A problem here is that _create_hash_desc is called many times to
create a TupleDesc with int32 attribute.
I've tried to implement the function like this ,
TupleDesc _create_hash_desc()
{   static bool firstcall = true;   static TupleDesc tupdesc;   if(firstcall){       tupdesc =
CreateTemplateTupleDesc(1,false);       TupleDescInitEntry(tupdesc, 1, "hashcode", INT4OID, -1, 0);   }   firstcall =
false;  return tupdesc;
 
}

but it failed because tupdesc is free later, IMHO.
Any advice?
