Could not open file pg_xlog/000000010....

Hello, my name is Viktor, I am from Ukraine.

I work under ArchLinux.
I have installed Postgresql 8.4.4 and I can't run it.

Report log:

I hadn't this problem under previous version Postgresql 8.4.3.
I tried pg_resetxlog -f /var/lib/postgres/data, but it didn't resolve
this problem.
I tried reinit database but result is the same.
