As Adrian mentioned, by the time you go for a startup of pgsql, the
damage is already done during the previous shut down.
The real issue here is that a properly operating server should be able
to have the power plug pulled, and on boot up postgres should be able
to come back up. When pgsql can't come back up, it's usually due to an
unreliable storage subsystem. So what are you using for storage?
