Huh?  IIRC you can change all the checkpoint parameters with SIGHUP.
You can *not* set them per-connection, that just doesn't make any
physical sense considering that the behavior involved is cluster-wide.

I doubt that checkpoint_timeout is very important to raise anyway.
Now checkpoint_segments is something you might well need to raise...
