ZeroFill(.../pg_xlog/xlogtemp.20148) failed: No such file or directory

I got this error while trying to restore a full dump:

psql:/home/olly/db.out:93439: FATAL 2: copy: line 37292,
ZeroFill(/var/lib/postgres/data/pg_xlog/xlogtemp.20148) failed: No such file
or directory
psql:/home/olly/db.out:93439: PQendcopy: resetting connection
psql:/home/olly/db.out:157137: connection to server was lost

Has anyone any idea for a cure?

"We are troubled on every side, yet not distressed; we

the life also of Jesus might be made manifest in our
body." II Corinthians 4:8-10
