Selective quoting of the log output?  Naughty naughty.

However, that still doesn't explain how you got into the current state.
Had you once had checkpoint_segments set much higher than the current
value of 24?  On looking at the code I see that it doesn't make any
attempt to prune future log segments after a decrease in
checkpoint_segments, so if a previous misconfiguration had allowed the
number of future segments to get really large, that could be the root of
the issue.
