It's only worth worrying about if you see it regularly.
There is some documentation about this in the administrator's guide, eg
http://candle.pha.pa.us/main/writings/pgsql/sgml/wal-configuration.html
(That's 7.2 docs and some of the statements are not true for 7.1, but
it's close enough, and I think the exposition is better than in the 7.1
docs.)
