You don't have to drop it, you can create another db by any other name and
re-run the sql file there. The only time you have to worry is if you use
the -C (--create) option to pg_dump. This would actually issue a 'create
database' command in the sql dump. But for you, you can restore to another
database if you would like. That being said, if this is production, I would
be careful to not 'accidentally' run the sql file against the wrong
database, so for your own sanity, you may want to just drop the db. But
there's no *requirement* that you do so.
