The user swkm is the user I use to create backups manually. The script itself is executed fine if run manually but run on cron scheduler I got an mydb_dump_$time.out file empty (of 0 kb) Do you have any idea about what's wrong? you have to pass the -U argument to pg_dump, otherwise it'll try to run the script as root jef Thanks Sorin ---(end of broadcast)--- TIP 9: In versions below 8.0, the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match ---(end of broadcast)--- TIP 3: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faq

Hello Sorin! Sorin N. Ciolofan wrote: #!/bin/bash time=`date '+%d'-'%m'-'%y'` cd /home/swkm/services/test pg_dump mydb mydb_dump_$time.out You should output STDERR to some error logfile or set MAILTO in your crontab. I guess you then would have seen an error message saying that pg_dump was not found because cron doesn't load the users environment and therefore PATH variable isn't set. I suggest you call pg_dump in your script by absolute path. Greetings, Frank Wittig signature.asc Description: OpenPGP digital signature

Thank you all, Yes, I used the absolute path in my script and now works ok :-) Thank you again Sorin -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Frank Wittig Sent: Thursday, November 22, 2007 4:01 PM To: Sorin N.
