  1. Manual Failover

    Yongye Serkfem <yserkfem@gmail.com> — 2024-06-19T15:03:30Z

    Hello Engineers,
    I am facing an issue with the manual failover of the standby to the master
    role. I was able to promote the standby and got it out of recovery mode.
    How do I direct applications to point to the standby which has assumed the
    role of the current master, and what should I do after completing
    maintenance on the previous master to assume its original role as master?
    I would appreciate any input, and thank you for your time.

    You need to show your set up (failover script, etc) but usually the 
    standby get the ip address of the now-dead master and the apps are none 
    the wiser.

    A typical solution is a separate service which manages a virtual IP that
    points to whichever DB server you choose.

    pg_basebackup is guaranteed to get previous-master in sync with
    now-active.  pg_rewind might also work.
