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.
