Bug reference: 7703
Logged by: Maksym Boguk
Email address: maxim(dot)boguk(at)gmail(dot)com
PostgreSQL version: 9.2.1
Operating system: Any
Description:

Simple test case:

test=# create table test (id serial);
NOTICE: CREATE TABLE will create implicit sequence "test_id_seq" for serial
column "test.id"
CREATE TABLE
test=# create index test_id_key on test(id);
CREATE INDEX
test=# create table test_part_1 (like test including all) INHERITS (test);
NOTICE: merging column "id" with inherited definition
CREATE TABLE
test=# 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.
