it depends entirely on your application. There is no "one size
fits all"
For example to have an online backup, WAL archiving to remote
sites is often sufficient.
However you cannot have synchronous multimaster replication
over slow lines and high performance with updates the same
time.
There is always a tradeoff in any (even in high cost
commercial solutions) you have to carefully consider.

This would remove the application using that data too, or not? ;)
