grant user access - Mailing list pgsql-general

I'm stuck.

How do I grant select, insert, delete, update rights to an entire database?

I tried this:

GRANT SELECT, INSERT, UPDATE, DELETE ON DATABASE foo TO bar;

and it returns
ERROR:  syntax error at or near "INSERT" at character 14

I'm just not getting it, it sure looks like I should be able to.
I'm logged in as postgres.
