pg_restore：[存档（db）]处理目录时出错：

Question

I have restored a database using pg_restore. I found that data is restored but it throwed a few errors. What's the reason for these errors?

This is the command using for restoring

pg_restore -U postgres -d newdb08aug19 -j5 remote

What's the reason for these kind of errors?

Answer 1

You only dumped part of the database (probably using something like -n finance , which would only dump objects in that schema).

So the foreign key constraints that reference table that are not included in the dump will cause an error message when the dump is restored.

Everything except the constraints will be restored correctly.
