I'm not doubtful that this is a good idea. There are a number of tableams around these days that are "heap except whatever", where (I suspect) the size of "whatever" ranges from quite small to moderately large. I imagine that such efforts end up duplicating a lot of heapam code and probably always will; but if we can avoid increasing that amount, I think it's a good idea. -- Robert Haas EDB: http://www.enterprisedb.com
