Hmm, how exactly was the failover managed?

The xlogtemp files are a bit suspicious; they shouldn't be there. The
timestamps suggest that something odd was going on right after the
failover. Do you have the slave's postmaster log from that time
interval, and if so, does it show anything out of the ordinary?
