I like that better, because it lets us retain an escape valve in case we should need it. I suggest that the documentation should say things like "The default is believed to be suitable for most use cases" or "We are not aware of a reason to change the default" rather than something like "There is almost certainly no good reason to change this" or "What kind of idiot are you, anyway?" :-) -- Robert Haas EDB: http://www.enterprisedb.com
