I have no objection to do that, but we will need other default values soon, something like default_[heap|btree|hash|gist|gin]_fillfactor. Some of us might feel it is mess to add random guc variables. > HOT works much > better if there is atleast one tuple worth of free space in each block. I find it is more important. You say *number-of-tuples* is more suitable unit for fillfactor than *percentage*. It might be good to reconsider the unit when we add a database wide GUC parameter. It could be that there are a tables with 80 bytes length of tuples (1%) and one with 800 bytes length (10%) in the same database.
