Обсуждение: How to check for pg_dump errors?

Silly question, but in a shell script, what is the best way to check for a pg_dump problem?  I'm working on reworking our backup methodology, and want to make sure that if pg_dump can't dump a db, we page the on call db.  Does it return any sort of exit code indicating it was not successful dumping a database?

Thanks,

Chris

pg_dump should return nonzero exit code on failure.  (At least in recent
releases ... not sure about how far back that's been done consistently.)

0 is success, nonzero is failure.
