Try

CREATE TABLE active_sessions (
  sid varchar(32) DEFAULT '',
  name varchar(32) DEFAULT '',
  val text,
  changed varchar(14) DEFAULT '' NOT NULL,
  PRIMARY KEY (sid,name),
);

CREATE [UNIQUE] INDEX {index_name} ON active_sessions USING btree(changed);

-- NOT NULL is implied in a primary key

And:

CREATE TABLE auth_user (
  uid varchar(32) PRIMARY KEY DEFAULT '',
  username varchar(32) DEFAULT '' NOT NULL,
  password varchar(32) DEFAULT '' NOT NULL,
  perms varchar(255)
);

CREATE UNIQUE INDEX username_k ON auth_user USING btree(username);

--  Though correct syntactically,  a DEFAULT for any key column rarely makes
good sense.

\h create table

-- at the psql prompt display allowable syntax
