I have a recover situation related to:
Oct 13 23:04:58 66-162-145-116 postgres[16955]: [1-1] LOG: database system was shut down at 2007-10-13 23:04:54 PDT

Based on what I've read on the mail archives, the recommended fix is to create file '00A4' and fill it with 256k zeros. Is there a quick and easy linux-way of creating such a beast?
