We have used asynchronous replication across datacenters with 100%
success since 9.1. Currently we use 9.2.
Our setup involves a internet tunnel between servers. Servers have about
2.000km of distance from each other.
The only points you need to take attention is tuning number of
wal_keep_segments and timeout, and the initial load (that can be huge,
depends on your data).
