how to fail over slave to master

[Pepe TD Vo <pepevo@xxxxxxxxx>]

Hello,

I have a problem with my master's Postgresql service.  I can't start up Postgresql, something corrupted and the Postgresql service is down.  The slave is still up and running, I wonder how to turn slave to primary and fixing the master server.  Once the master server is fixed, how can I fail it back?

Please advise.

To call him a dog hardly seems to do him justice though in as much as he had four legs, a tail, and barked, I admit he was, to all outward appearances. But to those who knew him well, he was a perfect gentleman (Hermione Gingold)
