postgres=# create global temporary table gtt(c1 int) on commit preserve rows; CREATE TABLE
postgres=# create materialized view mvw as select * from gtt; ERROR: materialized views must not use global temporary tables or views
Anyways we are not allowed to create a "global temporary view",
so the above ERROR message should change(i.e. " or view" need to be removed from the error message) something like: "ERROR: materialized views must not use global temporary tables"
