Grant privileges on future tables in PostgreSQL?

Question

I am running PostgreSQL 9.3.1. I have test database and backup user which is used to backup the database. I have no problems with granting privileg

Answer 1

It looks like the solution is to alter default privileges for backup user:

alter default privileges in schema public grant all on tables to backup;
alter default privileges in schema public grant all on sequences to backup;

From the comment by Matt Schaffer:

As caveat, the default only applies to the user that executed the alter statement. This confused me since I was driving most of my permissions statements from the postgres user but creating tables from an app user. In short, you might need something like this depending on your setup:

ALTER DEFAULT PRIVILEGES FOR USER webapp IN SCHEMA public GRANT SELECT ON SEQUENCES TO backup;
ALTER DEFAULT PRIVILEGES FOR USER webapp IN SCHEMA public GRANT SELECT ON TABLES TO backup;
