This option is not valid unless --clean is >also specified. By doing it 1 command at a time with lots of compares, I think I'm starting to understand what's going on. Documenting this for those who are curious and to help others in the future... Back to the part where I have the data spread over 2 schemas... Note that I'm trying to backup only 1 at a time. The reason for doing this is because the important data is in the public schema, while the other schema is for logging data and will be 100's of times bigger (we do back this up but not as often because losing a little is not fatal). Anyway, when I change the public schema to a new name, the tables in the logging schema that use types from public automatically change, e.g. from public.call_types to savepublic.call_types. That also means that if I were do "drop schema public cascade", then the logging table definitions gets changed as the column is dropped. Yikes! (Sadly, I should have realized this before but didn't.) But that's why I'm getting the errors, because when I try to restore the public schema, our custom types do already exist. To your suggestion of added "--if-exists --clean", that does remove 4 errors, leaving me with 14 that are true errors. My take away from this is that if we have schemas that are dependent on each other, we can't backup/restore just 1. That means we must break the dependency or else back them both up all the time (not desirable to do this frequently because of size). Sigh... I'll go back and look at what it would take to break the dependencies, but any other suggestions would be welcome. Thanks for the advice and pointers Adrian!
