How to fix permission denied for schema in PostgreSQL

Question: When attempting to create a PostgreSQL table with the CREATE TABLE command I get an error message:

ERROR: permission denied for schema northland_claims LINE 1: create table mytest(ID int); ^ SQL state: 42501 Character: 14

How can I fix? 

This is the current DDL of the user:

CREATE USER myuser WITH ENCRYPTED PASSWORD 'xxxxxxx';
GRANT CONNECT ON DATABASE mydb TO  myuser;
GRANT USAGE ON SCHEMA myschema TO myuser;
GRANT SELECT, INSERT, UPDATE, DELETE ON ALL TABLES IN SCHEMA myschema TO myuser;

Answer:   To fix this error you'll need to add an extra permission on the schema.    In the example you've given above you'll need to change the GRANT USAGE statement & add the CREATE  command

GRANT USAGE,CREATE ON SCHEMA myschema TO myuser;

From the PostgreSQL documentation - "There is no need to grant privileges to the owner of an object (usually the user that created it), as the owner has all privileges by default. (The owner could, however, choose to revoke some of their own privileges for safety.)"
