I'm confused by this report too. Plain crashes shouldn't result in
forking a new timeline. To check, I tried "-m immediate", as well as
"kill -9 postmaster", and neither of those resulted in a new .history file
on restart. I wonder if the OP's restart process involves calling
pg_resetxlog or something like that (which would be risky as heck).
