I have used the Streaming Replication guide on the PostgreSQL Wiki to configure replication between my two db servers.
But, when I updated a row on master server it is available on the slave instantly. It should be asynchronous, isn't it? What I am missing?
Servers are in separate places. The master's upload speed is ~75kb/sec. As far as I know, first of all, 16MB xlog file should be upload to slave, after that transactions available on slave. But it is happening in 1 sec. Why is it so fast?
