What OS, pg version etc are you running?

If windows, are you running any anti-virus software? A lot of
anti-virus packages are dumb as a brick and lock files when checking
them and cause these problems. If so, either exclude the pg
directories from virus checking or turn it off altogether.

Just a guess. Not enough info to really know.
