Re: pg_dump from crontab

[Adam Radlowski <adamr(at)informatyka(dot)gdansk(dot)pl>]

Try (do not use ">" output stream redirection, but "-f" switch):
0 20 * * 5 /usr/pgsql/bin/pg_dump -F c database -f 
/usr/backup/friDATE4.pgdump
0 20 * * 4 pg_dump -F c database -f /usr/backup/thurDATE06-3.pgdump
Or instead (if it will not work):
1. Put those commands into root crontab file (/var/spool/cron/root)
2. Instead raw putting the commands into crontab file, put them into 
scripts and run for them the shell - for example:
0 20 * * 5 /bin/sh /home/scripts/fri_date4.sh
0 20 * * 4 /bin/sh /home/scripts//thur_date06-3.sh

Into /home/scripts/fri_date4.sh You put line:
/usr/pgsql/bin/pg_dump -F c database -f /usr/backup/friDATE4.pgdump
Into /home/scripts//thur_date06-3.sh You put line:
pg_dump -F c database -f /usr/backup/thurDATE06-3.pgdump
