Indeed, using the same example as the docs:
CREATE TABLE measurement (
     logdate         date not null,
     peaktemp        int,
     unitsales       int
 ) PARTITION BY RANGE (logdate);
CREATE TABLE measurement_y2016m07
     PARTITION OF measurement (
     unitsales DEFAULT 0
 ) FOR VALUES FROM ('2016-07-01') TO ('2016-08-01');
SET enable_partition_pruning = on;
EXPLAIN SELECT count(*) FROM measurement WHERE logdate = DATE
'2016-07-02';

I'll take care of committing that, however this will have to wait
until v12 RC1 is tagged.
