环境

Postgresql :8.1.11

问题

The customer want to use pg_dump utility in some script to weekly backup of PostgreSQL DB.

And they want to know about return codes of pg_dump command.

决议

I Confirmed the source code of pg_dump, and I found that it include only two exit code.

0--> exit normally

1--> indicate some error.

If pg_dump finished with exit code 1, it also provides error message.

And pg_dump doesn't return other specific error codes but  '1'.

根源

N/A

诊断步骤

Read Source code.
