I think it's a bad idea to change the meaning of a pre-existing option
letter, and a worse idea to change pgbench's default behavior.  Instead,
have the option be "--checkpoint  do a CHECKPOINT after initialization".

It doesn't look like there's any free single-letter option that goes
nicely with "checkpoint" either, but that's life.
