Shouldn't the above be in a shell script? In this way, the commands
will be executed sequentially. Executing them concurrently does not
seem to be what you intended.

The above is a harsh way to determine whether or not cron is working. I
would use the following test instead:
*/1 * * * * date >>/tmp/date.txt

See above.
To further debug this problem, I would do one of the following:
1. set up ssmtp and set MAILTO as appropriate
2. redirect stdout and stderr to a log file
so cron can inform you of any output (i.e., errors) from the cron jobs.
BTW, what user is the crontab running under? Is it the same one as used
during the command line testing?

Good.

Change the above to the following:
9 12 * * * /c/progra~1/apache~1/apache/cgi-bin/backupsys >>/tmp/backupsys.log 2>&1
Does examining the contents of /tmp/backupsys.log help you debug the
problem?

Does the cron job run as the same user as the one invoking the command
line? For example, what does the following cron job indicate?
*/1 * * * * id >>/tmp/id.txt
And, what does the following indicate?
$ id
Do they agree?

Sorry, I don't know. Is your /etc/passwd and /etc/group files set up
correctly? Is cron really switching users correctly?
BTW, I get the following:
$ id
uid=19695(jt) gid=10513(Domain Users) groups=544(Administrators),545(Users),10513(Domain Users)
$ cat /tmp/id.txt
uid=19695(jt) gid=10513(Domain Users) groups=544(Administrators),545(Users),10513(Domain Users)
Sounds like your Cygwin setup is not correct.

Unless you are really running under the local administrator's account, then it appears that your /etc/passwd and /etc/group files need to be regenerated with mkpasswd and mkgroup, respectively. Please take this problem to the Cygwin list <cygwin@cygwin.com> since this is really OT for this one. Additionally, since there are more experienced Cygwin users there, your problem is likely to be solved faster than here.

Jason,
Actually I do have these in a shell script file name "backupsys"
vacuumdb --username=jeff -h localhost jeffdb
pg_dump --username=jeff jeffdb >
> /c/progra~1/apache~1/apache/ intrapos/database/intrapos_shdw.dat
pg_ctl stop -m fast
My cron really looks like this:
9 12 * * * /c/progra~1/apache~1/apache/cgi-bin/backupsys
Thanks

From $id
uid=500(Administrator) gid=513(None)
groups=544(Administrators),545(Users)
From cron
uid=500(Administrator) gid=513(None) groups=513(None),545(Users)
The groups are different. Why is that?
Thanks

Sorry Jason,
I don't know. How do I know if cron is switching user correctly? How
can I reconfigure /etc/passwd and /etc/group files so cron will work
correctly? Will mkgroup and mkpass correct this problem?

Sorry, I don't know. Is your /etc/passwd and /etc/group files set up
correctly? Is cron really switching users correctly?
BTW, I get the following:
$ id
uid=19695(jt) gid=10513(Domain Users)
groups=544(Administrators),545(Users),10513(Domain Users)
$ cat /tmp/id.txt
uid=19695(jt) gid=10513(Domain Users)
groups=544(Administrators),545(Users),10513(Domain Users)
Sounds like your Cygwin setup is not correct.
