As of now there is no solution for this in PostgreSQL but I had submitted a patch "Standalone synchronous master" in
9.4 2014-01 CommitFest, which was rejected because of some issues. This patch was meant to degrade the synchronous
level of master, if all synchronous standbys are down.
I plan to resubmit this with better design sometime in 9.5.
