I've been wondering what obscure hazards these "tombstone" (for want of a better word) files guard against, besides the one described in the comments for mdunlink(). I've been thinking about various schemes that can be summarised as "put the tombstones somewhere else", but first... this is probably a stupid question, but what would break if we just ... turned all this stuff off when wal_level is high enough (as it is by default)?
