Re: Copy & Re-copy of DB

create database is to create a new database.  If we switch to new database, we need to change the new databasename in the program(s) that access this database.  
Is there any way to overwrite the data ?

create database <new-db-name> template <old-db-name>

Would that do the job? You could also use pg_dump.
