The usual trap in cron usage is the fact that crontab commands are executed
in a cleanroom environment, ie no environment variable is used/inherited, so
PATH, HOME, PGDATA, etc are not set/available when the command is launched.

You can set vars or be very explicit in your script including DB names, DB
Users, etc
