Write permissions for PgAgent user to target location?

SELinux involvement?


Also, you seem to be doing both a pg_dumpall that backs up all the 
databases, and individual pg_dump runs for each database. Typically 
you'd do one or the other. If using individual database pg_dump, you 
usually use pg_dumpall with the "--globals-only" option to capture user 
definitions etc.


I recommend that you add error handling to your script. First, add

set -e -u

to the top, so the script treats undefined variables as errors and so 
that it aborts when commands fail. Then add error handling, eg:

$PGBIN/pg_dumpall -h $PGHOST -U $PGUSER | gzip > 
$BACKUPDIR/fullbackup-$themonth.sql.gz

becomes (eg)

if ! "$PGBIN/pg_dumpall" -h "$PGHOST" -U "$PGUSER" | gzip > 
"$BACKUPDIR/fullbackup-$themonth.sql.gz" ; then
   echo >2 "Failed to dump global data from database. Backup FAILED."
   exit 1
fi

Then make *SURE* that cron or pgagent or whatever check the exit status 
of your script and email you the contents of stderr when it fails. Do 
this by temporarily adding:

echo 2>"Manually aborting"
exit 1

to the top of your script and making sure that you get an error email 
containing "Manually aborting" when it is there.

Once that's done, you'll know that if something makes the backup fail, 
you will be notified and the message will contain the error output from 
the failed command.
