It's supposed to work.

Hmm, I see a bug in btree_redo handling of XLOG_BTREE_REUSE_PAGE. If hot
standby is not enabled in the standby, it chokes on that record type.
It's missing from btree_desc too.

Fixed.

This demonstrates that there really has been little testing of warm
standby with hot standby disabled :-).
