You may want to look into the "template" parameter of CREATE DATABASE. Whenever a database is created it's actually just copied from an existing database. It normally comes from "template1", which is a basically empty and clean database that it's initialized when the cluster is created (installed). If you have lots of databases that are basically the same and unchanging, you may want to create the tables in one database (say "clienttemplate") and do: CREATE DATABASE client101 TEMPLATE 'clienttemplate'; and all the tables/views/stored procedures/other definitions in the template will be automatically copied into the new database. One caveat, is that this is a once only operation. Once the new database has been created, the link back to the template is lost so any subsequent changes in the template won't also happen in the new database. For more details have a look at [1].
