Since you've got checkpoint_segments = 256, the xlog code will allow as many as 513 (2*checkpoint_segments+1) not-yet-used xlog files to be allocated. The only simple way to tell where the end of WAL is at the moment is to look for the xlog file with the latest mod time. (There'll be more support for this in 8.2.) Any files with names numerically larger than that one are just sitting there waiting to be used, they are not interesting for archiving purposes. regards, tom lane
