Partitioned tables and covering indexes

Hi,

Trying covering indexes on partitioned tables i get this error
"""
postgres=# create index on t1_part (i) include (t);
ERROR: cache lookup failed for opclass 0
"""

To reproduce:

create table t1_part (i int, t text) partition by hash (i);
create table t1_part_0 partition of t1_part for values with (modulus
2, remainder 0);
create table t1_part_1 partition of t1_part for values with (modulus
2, remainder 1);
insert into t1_part values (1, repeat('abcdefquerty', 20));

create index on t1_part (i) include (t);
