Hi Sorintlab,
please consider the enhancement:
In 2 nodes cluster it makes sense to deactivate the synchronous replication from the master to slave in case the slave fails (or network is splitted) and restore it when the slave backs online.
Seems it should be the option.

Basic ideas:

1. Though the slave fails the master still contains the correct data and database clients are connected to the master. From their point of view the database is still online.
