I've been testing the v9 patch with checksums enabled and I end up with a lot 
of warnings like these ones:

WARNING:  page verification failed, calculated checksum 47340 but expected 
47342
WARNING:  page verification failed, calculated checksum 16649 but expected 
16647
WARNING:  page verification failed, calculated checksum 13567 but expected 
13565
WARNING:  page verification failed, calculated checksum 14110 but expected 
14108
WARNING:  page verification failed, calculated checksum 40990 but expected 
40988
WARNING:  page verification failed, calculated checksum 46242 but expected 
46244

I can reproduce the problem with the following script:

WORKDIR=/home/fcanovai/tmp
psql -c "CREATE DATABASE pgbench"
pgbench -i -s 100 --foreign-keys pgbench
mkdir $WORKDIR/tbsp
psql -c "CREATE TABLESPACE tbsp LOCATION '$WORKDIR/tbsp'"
psql -c "ALTER DATABASE pgbench SET TABLESPACE tbsp"

Regards,
Francesco
