Thanks Wenjing. The reported  issue is fixed now  but  there is an 
another similar  scenario -
if we enable 'on_commit_delete_rows' to true using alter command then 
getting same issue i.e rows are not removing after commit.

x=# create global  temp table foo123(n int) with 
(on_commit_delete_rows='false');
CREATE TABLE
x=#
x=# alter table foo123 set ( on_commit_delete_rows='true');
ALTER TABLE
x=#
x=# insert into foo123 values (1);
INSERT 0 1
x=# select * from foo123;   <- row should get removed.
