Postgresql – ny maximum number of tables for Postgresql in one database

I thought it might be helpful to mention that, as of 9.0, postgres does have the syntax to grant privileges on all tables (as well as other objects) in a schema:

GRANT SELECT ON ALL TABLES IN SCHEMA public TO user;
GRANT EXECUTE ON ALL FUNCTIONS IN SCHEMA public TO user;

Here's the link.

The answers to your questions come from the online PostgreSQL 8.4 docs.

1. GRANT ALL PRIVILEGES ON DATABASE grants the CREATE, CONNECT, and TEMPORARY privileges on a database to a role (users are properly referred to as roles). None of those privileges actually permits a role to read data from a table; SELECT privilege on the table is required for that.

2. I'm not sure there is a "proper" way to grant all privileges on all tables to a role. The best way to ensure a given role has all privileges on a table is to ensure that the role owns the table. By default, every newly created object is owned by the role that created it, so if you want a role to have all privileges on a table, use that role to create it.

   PostgreSQL 9.0 introduces the following syntax that is almost what you want:

   GRANT ALL PRIVILEGES ON ALL TABLES IN SCHEMA public TO new_user;

   The rub is that if you create tables in schemas outside the default "public" schema, this GRANT won't apply to them. If you do use non-public schemas, you'll have to GRANT the privileges to those schemas separately.
