Thanks Wenjing.

I am getting this error  "ERROR:  could not open file 
"base/13589/t3_16440": No such file or directory" if 
max_active_global_temporary_table set to 0

Please refer this scenario -

postgres=# create global temp table  tab1 (n int ) with ( 
on_commit_delete_rows='true');
CREATE TABLE
postgres=# insert into tab1 values (1);
INSERT 0 1
postgres=# select * from tab1;
  n
---
(0 rows)

postgres=# alter system set max_active_global_temporary_table=0;
ALTER SYSTEM
postgres=# \q
[tushar@localhost bin]$ ./pg_ctl -D data/ restart -c -l logs123

waiting for server to start.... done
server started

[tushar@localhost bin]$ ./psql postgres
psql (13devel)
Type "help" for help.

postgres=# insert into tab1 values (1);
ERROR:  could not open file "base/13589/t3_16440": No such file or directory
