Hello... Here is procedure of making everyday online backup: 1) select pg_start_backup('xxx'); 2) tar -cf backup-xxx.tar /mnt/db/pg1 3) select pg_stop_backup(); rm all archived WAL files before special one taken from backup_log 4) tar -cf var-xx.tar /mnt/db/var Next I'd like to use this copy on my test machine. So I copy backup-xxx.tar and var-xxx.tar and untar these files. Directories structure on test are the same like on production machine. But when I try to run pg_ctl only empty log file is created but postmaster doesn't run. Can anyone please tell me what I'm doing wrong? Thx, Marcin
