Oh, I'm on board with increasing the default size a bit. A different default size isn't a non-default compile time option anymore though, and I don't think 1GB is a reasonable default. Running multiple archive_commands concurrently - pretty easy to implement - isn't the same as removing the need for archive command. I'm pretty sure that continously,and if necessary concurrently, archiving a bunch of 64MB files is going to work better than irregularly creating / transferring 1GB files.
