I saw that too, but it doesn't seem to explain 20GB worth of pg_xlog.
The fine manual mentions somewhere that we can keep up to twice the
specified number of xlog segments, so one would expect at most 16MB
* 600 or about 9.6GB in pg_xlog. (And this is assuming that
checkpoint_timeout is large enough to let checkpoint_segments be the
controlling factor.) So there's something else going on.
