I create partitions as below.
And run query: select * from test where grupa='A';
Is planner skip to analyze partitions: test2d, test2e, test2f ?
best regards

CREATE TABLE test (
grupa character varying(1),
id integer,
num integer NOT NULL
);
CREATE TABLE test1 (CONSTRAINT "ABC" CHECK (((grupa >= 'A'::text) AND (grupa <= 'C'::text))))
INHERITS (test);
CREATE TABLE test1a (CONSTRAINT "A" CHECK ((grupa = 'A'::text)))
INHERITS (test1);
CREATE TABLE test1b (CONSTRAINT "B" CHECK ((grupa = 'B'::text)))
INHERITS (test1);
CREATE TABLE test1c (CONSTRAINT "C" CHECK ((grupa = 'C'::text)))
INHERITS (test1);
CREATE TABLE test2 (CONSTRAINT "DEF" CHECK (((grupa >= 'D'::text) AND (grupa <= 'F'::text))))
INHERITS (test);
CREATE TABLE test2d (CONSTRAINT "D" CHECK ((grupa = 'D'::text)))
INHERITS (test2);
CREATE TABLE test2e (CONSTRAINT "E" CHECK ((grupa = 'E'::text)))
INHERITS (test2);
CREATE TABLE test2f (CONSTRAINT "F" CHECK ((grupa = 'F'::text)))
INHERITS (test2);
