Vacuum full GTT, cluster GTT is already supported in global_temporary_table_v24-pg13.patch.

Here , it is skipping GTT

You are now connected to database "foo" as user "tushar".
foo=# create global temporary table  g123( c1 int) ;
CREATE TABLE

The message was inappropriate at some point, so I removed it.

Thanks Wenjing. Please see -if this below behavior is correct

X terminal -

postgres=# create global temp table foo1(n int);
CREATE TABLE
postgres=# insert into foo1 values (generate_series(1,10));
INSERT 0 10
postgres=# vacuum full ;
VACUUM

Y Terminal -

[tushar@localhost bin]$ ./vacuumdb -f  postgres
vacuumdb: vacuuming database "postgres"
