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
