BUG: Session getting disconnected while executing a function to create materialised views in PostgreSQL 9.6

Dear Team,

While creating a 9.6 database environment we have come across a situation where the session is getting disconnected while running a function. Below are the DB details and function details.

DB Version: PostgreSQL 9.6beta3 on x86_64-pc-linux-gnu, compiled by gcc (GCC) 4.4.7 20120313 (Red Hat 4.4.7-17), 64-bit
DB Client: PgAdmin 3 v1.22.1
DB Client Operating System: Mac OS v10.11.3

DB Function definition (sample test function to replicate the issue):-
CREATE OR REPLACE FUNCTION testing_func()
RETURNS void AS $$
BEGIN

DROP MATERIALIZED VIEW IF EXISTS test1;

CREATE MATERIALIZED VIEW test1 AS
(
SELECT 1 as a,2 as b,3 as c,4 as d,5 as e,6 as f
ORDER BY
1
) WITH NO DATA;

END;
$$ LANGUAGE plpgsql;

Replication Scenario:

* Compile the above code. Run select query of the above function (I.e. Select testing_func();)

Result:

* Session gets disconnected forcibly.

Few other observations:

* The same code snippet runs fine in PostreSQL v9.5
* When we remove the clause WITH NO DATA, then the functions runs successfully

Please let me know in case any more details are required from our side.
