My application is general purpose accounting and sales application. If database does not exists, it prompts user and creates new database containig some hundreds of tables and upsizes local data to database. Each database can have a lot of schemas. Each schema represents a single company. All those schemas have exactly the same tables, each schema contains 80 tables. In public schema I store tables common for all companies (60 tables). So I seems that my application needs to be run with super-user privileges in Postgres.
