Safe switchover

Hi all,

I’m trying to work out a procedure for a safe zero data loss switchover
under (high) load, which allows the old master to be reconnected without
the use of pgrewind.

Would the following be sane?

- open connection to database
- smart shutdown master
- terminate all other connections
- wait for shutdown (archiving will finish)
- Identify last archived WAL file name (ensure it’s on backup server.)
- wait till a standby has applied this WAL
- promote that standby
- attach old master to new master

Cheers,
James Sewell
