Oh, the *directories* were getting big, not the files? (Normally
pg_clog files do not grow beyond a certain, rather small size, which is
why I was asking) Yeah, they are bound to lose or corrupt data sooner
rather than later. If they ever see their system crash, it won't be
able to recover due to pg_xlog deletion. (Note that pg_xlog is quite
different from pg_clog). pg_clog deletion guarantees that they will
have problem vacuuming or something.
