Hi,
we tried new feature RLS - tested on postgres 9.5.3 / CentOS6. When we turn on ENABLE RLS + FORCE RLS on normal workload cause huge produce checkpoints (about 30x or more), our disk partition for xlog was full and log shipping to replica maybe delayed removing old checkpoints. Have anybody same experiences after turn on RLS? Looks like more buffers set as dirty. Yes, we can provide more space for xlog, but it will take much more space for xlog backups. We do not know if it's worth it. We had log_checkpoints ON and I send log as attachment (RLS Turn ON at 13:26).
Thanks for any idea or explanation reasons if its normal behavior.
David
