Yes, it happens. I don't deny the problem, but I'm wondering about the wishful thinking we're possibly falling into here concerning the solution. Let's imagine that pg_xlog is named wal instead. How does that help our user with the disk space problem? Does that point to a path of resolution? I don't see it. What do we think that user's next move will be? After all, WAL means Write Ahead *Log*. On the other hand, by decommissioning pg_xlog as a name, that makes it obsolete in all presentations, tutorials, docs that refer to that directory, and there are many of them. There are years of confusion ahead with questions like "where is that pg_xlog directory that I'm supposed to monitor, or move into a different partition, etc...", for a benefit that remains to be seen.
