Обсуждение: How: single db, multiple users
Greetings, I am new to PostgreSQL and come from an DB2 background. I currently have v8.0.3 up and running. So far, it looks great! One area I am confused about is how to set up databases and users. I can currently create databases, but I am having difficulty in assigning mutiple users to those databases. For example, I have set up one database for a large project. There are several users that need to have access to that database: create tables, insert, delete, select, update, etc. The documentation talks about a single user-database associations but is not clear on how to have multiple users on a single database. Are there any best practices that I could follow in settings these up for various projects and databases? Or if this is a simple thing to do, any pointers on how to do it? __________________________________________ Yahoo! DSL Something to write home about. Just $16.99/mo. or less. dsl.yahoo.com
Postgres' users are not specific to a database, they are shared across all databases on a particular server. At the database level, you can assign creation and other permissions to users, but (AFAIK) you cannot deny users to a database. However, you can effectively control users' access to a particular database by granting or denying them access to a schema within that database.

It is quite helpful for me early in my introduction to PostgreSQL. So that I hear you correctly, it is OK then for only one user to be the owner of a database. Then I will give other users privileges on a one by one basis. And I can do this for a particular schema in a database or all schemas in it, without enumerating all the tables in those schemas? Am I correct? What kind of privileges do I need to give other users so that they can create tables, delete them, update them, etc. in that database? Can I use "ALL" priveleges here? __________________________________ Start your day with Yahoo! - Make it your home page! http://www.yahoo.com/r/hs
