The oldest log file that is not archived is:
-rw------- 1 postgres postgres 16777216 Aug 28 15:24
00000001000001930000005A

The command I am using is running successfully and I am getting good entries
in my log files.

So, it looks like everything is good, just the archive command is not
getting called enough.

Thanks,

Chris
