/* don't set signals, bgwriter has its own agenda */

+                       InitXLogInsert()

This is wrong, as the checkpointer is started as well on standbys, and
that InitXLOGAccess initializes things for WAL generation like
ThisTimeLineID.  So you should just call InitXLogInsert(), and a comment
would be welcome for both the bgwriter and the checkpointer.
