The PostgreSQL WAL log stores information on the level of "write these
bytes to disk", the MySQL replication log stores information on the
level of "user called this statement". So in MySQL, inserting the
value of now() into a table might give different results if a slave
runs in a different time zone. So it's sort of the same from the
outside, but the internals are different and yield different
possibilities and restrictions.
