I fixed in global_temporary_table_v16-pg13.patch.
Please refer this scenario -
--Connect to psql -
postgres=# alter system set max_active_global_temporary_table =1;
ALTER SYSTEM
--restart the server (./pg_ctl -D data restart)
--create global temp table
postgres=# create global temp table ccc1 (c int);
CREATE TABLE
--Try to Create another global temp table
postgres=# create global temp table ccc2 (c int);

I cannot find "max_active_gtt" GUC . I think you are referring to "max_active_global_temporary_table" here ?
also , would be great if we can make this error message user friendly like - "max connection reached" rather than memory error
