Well, I think that pulling the power cord is much safer than killing -9
the postmaster. If you pull the plug, then during bootup postgresql
will just replay every COMMITed transaction, so there won't be any
dataloss or downtime.
If you kill -9 the postmaster the system can still finish sending
changes to disk and close the file but pulling the power cord can stop a
write in the middle of a block giving you half new data and half old
data in the one file.
It's all a matter of timing.
