I think this is the case. We can even reproduce it: take another backup
of uncorrupted master and the slave is again corrupted.

The strange thing is that this only affects streaming replication
standby, not wal files shipping standby. Maybe we're doing something
wrong...

Could the reason for the strange behaviour (see previous mail) be
something different than corrupted index?

We'll try to reproduce it in testing environment and possibly create
reproducible test case. I'll definitely report back...
