\d doesn't show partitioned table foreign keys

[Amit Langote]

Hi.

I just noticed $subject, which attached seems to fix, although not sure if
that's the correct fix for the issue.

create table foo (a int primary key);
create table doo (a int primary key);
create table bar (a int references foo references doo) partition by list (a);
create table bar1 partition of bar for values in (1);

\d bar
                Table "public.bar"
 Column |  Type   | Collation | Nullable | Default
--------+---------+-----------+----------+---------
 a      | integer |           |          |
Partition key: LIST (a)
Number of partitions: 1 (Use \d+ to list them.)

But can see the key on the partition.

\d bar1
                Table "public.bar1"
 Column |  Type   | Collation | Nullable | Default
--------+---------+-----------+----------+---------
 a      | integer |           |          |
Partition of: bar FOR VALUES IN (1)
Foreign-key constraints:
    "bar_a_fkey" FOREIGN KEY (a) REFERENCES foo(a)
    "bar_a_fkey1" FOREIGN KEY (a) REFERENCES doo(a)

After applying the patch:

\d bar
                Table "public.bar"
 Column |  Type   | Collation | Nullable | Default
--------+---------+-----------+----------+---------
 a      | integer |           |          |
Partition key: LIST (a)
Foreign-key constraints:
    "bar_a_fkey" FOREIGN KEY (a) REFERENCES foo(a)
    "bar_a_fkey1" FOREIGN KEY (a) REFERENCES doo(a)
Number of partitions: 1 (Use \d+ to list them.)

Will add this to open items.

Thanks,
Amit
