However, it seems as though setting my checkpoint_timeout has no effect on checkpoint creation ( I have it set to 30 seconds). Forcing checkpoint by running */psql –c CHECKPOINT mydb/* doesn’t do the trick either. Checkpoints are created solely based on the checkpoint_segments logs reaching their configured size.


There is no such thing as checkpoint creation. Checkpoint timeout means that at 30 seconds (based on checkpoint_timeout) it will checkpoint unless it needs to do so sooner.

This is not satisfactory in a low transaction volume environment. Any hints on how else can I trigger checkpoint?

Thanks in advance,
