Thank you Wenjing for the new patch with the fix and the "VACUUM FULL GTT"
support.
I have verified the above issue now its resolved.
Please check the below findings on VACUUM FULL.
postgres=# create global temporary table gtt(c1 int) on commit preserve
rows;
CREATE TABLE
postgres=# vacuum FULL ;
WARNING: global temp table oldest FrozenXid is far in the past
