- When I run it as a job in postgres, it fails.  Here are the results:

- No schemas returned from database.  This could be a password issue.

- It is behaving like it could not login to get the schema list.
- Since prompting for a password is not an error message, it is not displayed
- in the error log.
- How can I debug this job?


As a sanity check you might want to add the following to the if statement.
echo "Hostname: ${HOSTNAME}"
echo "Username: ${USERNAME}"

Those may be getting lost when the job is run via cron.

For example:
# If the list of Schemas is empty, display error and abort
if [ "$FULL_BACKUP_QUERY_LIST" = "" ]; then
  echo "Hostname: ${HOSTNAME}"        # <-------Add
  echo "Username: ${USERNAME}"        # <-------Add
  echo -e "No schemas returned from database.  This could be a password
issue."
  exit 1
fi

Alternativly, add -x to the top line to enable debugging
#!/bin/bash -x

and then in your cron job output stdout and stderr to a file
0 0 0 0 0 0 backupjob.sh >/tmp/backup.out 2>&1
