Let's be nice and assume that you only lose one 8K block because of the
SSD write cache; that's not so bad, right? Guess what--you could easily
be the next lucky person who discovers the block corrupted is actually
in the middle of the pg_class system catalog, where the list of tables
in the database is at! Enjoy getting your data back again with that
piece missing. It's really a fun time, I'll tell you that.
