Description:
CREATE STATISTICS stts (dependencies) ON a, b FROM t;
ANALYZE t;
EXPLAIN (ANALYZE, TIMING OFF) SELECT * FROM t WHERE a = 1 AND b = 1;
QUERY PLAN
-------------------------------------------------------------------------------
Seq Scan on t (cost=0.00..195.00 rows=100 width=8) (actual rows=100
loops=1)
Filter: ((a = 1) AND (b = 1))
Rows Removed by Filter: 9900
The result of the explain is a copy paste of previous example, so this
example looks like the statistic doesn't improve things
