...snip.... Thanks Tom. Yes, no data change is required. But I don't think I have the understanding to try what you suggested. Running the alter table on my home database (almost same data) took an hour and it wasn't complete. I had even dropped the index. So I guess altering it that way is a pain in PGSQL.
