Hi Wenjing,

Please check the allowed values for boolean parameter "on_commit_delete_rows".

postgres=# create global temp table gtt1(c1 int) with(on_commit_delete_rows='true');
CREATE TABLE
Similarly we can successfully create GTT by using the values as: 'true','false', true, false, 'ON', 'OFF', ON, OFF, 1, 0 for boolean parameter "on_commit_delete_rows"

But we are getting error while using the boolean value as: '1', '0', 't', 'f', 'yes', 'no', 'y', 'n' as below.
postgres=# create global temp table gtt11(c1 int) with(on_commit_delete_rows='1');
ERROR:  on_commit_delete_rows requires a Boolean value
postgres=# create global temp table gtt11(c1 int) with(on_commit_delete_rows='0');
ERROR:  on_commit_delete_rows requires a Boolean value
postgres=# create global temp table gtt11(c1 int) with(on_commit_delete_rows='t');
ERROR:  on_commit_delete_rows requires a Boolean value
postgres=# create global temp table gtt11(c1 int) with(on_commit_delete_rows='f');
ERROR:  on_commit_delete_rows requires a Boolean value
postgres=# create global temp table gtt11(c1 int) with(on_commit_delete_rows='yes');
ERROR:  on_commit_delete_rows requires a Boolean value
postgres=# create global temp table gtt11(c1 int) with(on_commit_delete_rows='no');
ERROR:  on_commit_delete_rows requires a Boolean value
postgres=# create global temp table gtt11(c1 int) with(on_commit_delete_rows='y');
ERROR:  on_commit_delete_rows requires a Boolean value
postgres=# create global temp table gtt11(c1 int) with(on_commit_delete_rows='n');
ERROR:  on_commit_delete_rows requires a Boolean value

-- As per the error message "ERROR:  on_commit_delete_rows requires a Boolean value" either we should allow all the boolean values.

Example: CREATE VIEW view1 WITH (security_barrier = 'true') as select 5;

The syntax of VIEW allows all the above possible boolean values for the boolean parameter "security_barrier"

-- or else we should change the error message something like
"ERROR:  on_commit_delete_rows requires 'true','false','ON','OFF',1,0 as Boolean value".
