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.
