To Suggest a "DROP INCREMENTAL MATERIALIZED VIEW" in psql, but the syntax error when you run.

Hi.

I'm using the "Incremental Materialized View Maintenance" patch and have
reported the following issues.
(https://commitfest.postgresql.org/25/2138/)

To Suggest a "DROP INCREMENTAL MATERIALIZED VIEW" in psql, but the syntax
error when you run.
("DROP MATERIALIZED VIEW" command can drop Incremental Materialozed view
normally.)

ramendb=# CREATE INCREMENTAL MATERIALIZED VIEW pref_count AS SELECT pref,
COUNT(pref) FROM shops GROUP BY pref;
SELECT 48
ramendb=# \d pref_count
Materialized view "public.pref_count"
Column | Type | Collation | Nullable | Default
---------------+--------+-----------+----------+---------
pref | text | | |
count | bigint | | |
__ivm_count__ | bigint | | |

ramendb=# DROP IN
INCREMENTAL MATERIALIZED VIEW INDEX
ramendb=# DROP INCREMENTAL MATERIALIZED VIEW pref_count;
2019-11-27 11:51:03.916 UTC [9759] ERROR: syntax error at or near
"INCREMENTAL" at character 6
2019-11-27 11:51:03.916 UTC [9759] STATEMENT: DROP INCREMENTAL

ramendb=# DROP MATERIALIZED VIEW pref_count ;
DROP MATERIALIZED VIEW
ramendb=#

Regard.
