The background is that, over the years, a number of people deleted the pg_xlog and pg_clog directories when they noticed they're running out of space, thinking it's just server logs. Unfortunately that's the directories containing the database journal, and transaction status (committed/aborted/in-progress). Which means they'll loose data. The idea is to rename them to something that's less likely to be mistaken for unimportant data.
