Hello

I am having a problem with all slaves...i am not sure it's a bug or my side
configuration problem..

When ever i am restarting postgresql slave (Service postgresql restart -
made a script) or even just stopping and starting a postgresql slave.. it
displays a a message, although slave get's started and working fine...

`/usr/local/pgsql/data/pg_xlogarch/000000010000000300000026': No such file
or directory
cp: cannot stat
`/usr/local/postgres/data/pg_xlogarch/000000010000000300000026': No such
