It's the same as the slight issue I had: CREATE INDEX users_users_referrer_idx ON users_users(referrer) WHERE (referrer IS NOT NULL); usa=# explain analyze select * from users_users where referrer=1; QUERY PLAN ---------------------------------------------------------------------------- --------------------------- Seq Scan on users_users (cost=0.00..3.89 rows=8 width=235) (actual time=10.51..13.47 rows=8 loops=1) Filter: (referrer = 1) usa=# explain analyze select * from users_users where referrer=1 and referrer is not null; QUERY PLAN ---------------------------------------------------------------------------- ------------------------------------------------------------ Index Scan using users_users_referrer_idx on users_users (cost=0.00..3.01 rows=1 width=235) (actual time=17.12..17.36 rows=8 loops=1) Obviously to you and I, referrer=1 implies that referrer is not null, but the planner doesn't know that. You often have to add a redundant clause to the query to ensure that the partial index is used.
