I wrote a generic bash shell script to handle this kind of thing in cron.
See the attachment. As long as the program you're running returns an exit
value of 0 when it succeeds, and a non-zero value when it fails, this will
work. (Thought it's not documented in pg_dump's man page, it does return
sane exit values.)
Just do something like:
/path/to/cron-harness pg_dump your-arguments-here
If pg_dump succeeds, nothing will be output. If it fails, all the normal
output will be returned (and if this is a cron job, mailed to you, by
default).
Check the arguments to mktemp, which may vary on your platform. Any
suggestions or improvements are welcome!
HTH,
Jon
