Puh-lease.  TCP has solved that problem; look into the new algorithms and techniques PostgreSQL 9 brings to the ACID table.

Networks at layer 3 are expected to blip; TCP at layer 4 makes it a reliable stream.  Or if it goes down both endpoints know it went down, and the database engine has a choice whether to abort and rollback or wait on a retry.  Replay write-ahead logs are another way to deal with this.
