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. -- Peter Eisentraut http://developer.postgresql.org/~petere/ ---------------------------(end of broadcast)--------------------------- TIP 6: explain analyze is your friend
