If you've got a reasonably active database, 16MB/minute is not an unlikely rate of WAL generation. You can probably slow it down a bit by increasing the checkpoint-spacing parameters, but you can't just say "don't generate so much WAL please". Either you want a log or you don't. Basically, you have to take base backups often enough that the total number of WAL archive files needed stays under your threshold of pain... regards, tom lane
