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);

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
