The archive files are created by your archive_command, as specified in
postgresql.conf. My guess would be that your archive command runs the files
through gzip as part of archiving (which is fine).

However, the restore_command you specify in recovery.conf must undo this
compression. So instead of (for example) 'cp -f "%f" "%p"', it might instead
need to look like 'zcat "%f" > "%p"'.

Hope this helps.
