Bug reference:      7703
Logged by:          Maksym Boguk
Email address:      maxim.boguk@gmail.com
PostgreSQL version: 9.2.1
Operating system:   Any
Description:        =


Simple test case:

test=3D# create table test (id serial);
NOTICE:  CREATE TABLE will create implicit sequence "test_id_seq" for serial
column "test.id"
CREATE TABLE
test=3D# create index test_id_key on test(id);
CREATE INDEX
test=3D# create table test_part_1 (like test including all) INHERITS (test);
NOTICE:  merging column "id" with inherited definition
CREATE TABLE
test=3D# explain analyze select distinct min(id) from test;
ERROR:  failed to re-find MinMaxAggInfo record


PS: without partioning or without index over id - no error. Tested 9.0.*
versions is not affected by bug, but 9.2.1 and 9.1.6 is.
