Re: refreshing a database with pg_dump and psql

I will try the pg_restore –cC or drop the database first.
Thank you all for the quick response.

Hi,

I have a database that was created from a ‘pg_dump –C’. No problems there. Then I ran the pg_dump again, this time without the –C. and tried to load it. But got a bunch of ‘object already exist’.
Can’t I refresh an existing database from a plain pg_dump? Is there an option that I have to use?
Thanks.

Check the pg_restore manual. There is a "clean" option when using the custom format. I think this is what you are looking for.

​Or just inject a "DROP DATABASE ..." into the equation somewhere.

pg_restore -cC will do that, too.
