Hi all:

    As we know, the synchronous commit process is blocked while 
receives from acknowledgement from standby in

PostgreSQL.This is good for data consistence in master and standby, and 
application can get important data from standby.But

when the standby crash or network goes wrong, the master could be 
hang.Is there a feature plan for a semi sync like MySQL

InnoDB(set a timer, and become asynchronous when timeout)?
