create partition table caused server crashed with self-referencing foreign key

Hi,

Getting a server crash while creating partition table which have
self-referencing foreign key

postgres=# CREATE TABLE part1 (c1 int PRIMARY KEY, c2 int REFERENCES part1)
PARTITION BY LIST (c1);
CREATE TABLE
postgres=# CREATE TABLE part1_p1 PARTITION OF part1 FOR VALUES IN (1);
server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
The connection to the server was lost. Attempting reset: Failed.

--stack-trace
[edb(at)localhost bin]$ gdb -q -c data/core.16883 postgres
Core was generated by `postgres: edb postgres [local] CREATE TABLE
'.
Program terminated with signal 6, Aborted.
