REFRESH MATERIALIZED VIEW command in PL block hitting Assert

Hi,

I have observed that following sequence is causing server crash.

CREATE MATERIALIZED VIEW temp_class_mv AS
SELECT * FROM pg_class
WITH NO DATA;

CREATE OR REPLACE FUNCTION test_refresh_mv()
RETURNS int
AS $$
BEGIN
REFRESH MATERIALIZED VIEW temp_class_mv;
return 1;
END; $$ LANGUAGE plpgsql;

SELECT test_refresh_mv();

I had a quick look over the crash and it is hitting following Assert in
spi.c:

else if (IsA(stmt, RefreshMatViewStmt))
{
Assert(strncmp(completionTag,
"REFRESH MATERIALIZED VIEW ", 23) == 0);
_SPI_current->processed = strtoul(completionTag + 23,
NULL, 10);
}

It seems like we are missing expected value for completionTag in
ExecRefreshMatView()

Thanks
