If your Pgdata is safe the restore the DB using File system backup in fresh Postgresql instance and enable the Archive .
Or you take the db backup using pg_dump and restore on another fresh Postgresql installation .it is more suitable since you have already executed the pg_resetxlog.
Hi for anybody can help me. My colleagues have delete the files from the pg_xlog after that they did a px_resetlog and start de database and it's working now but when I set the archiving on in other path, this one doesn't work and the files from pg_xlog folder are not rotated.
