Hi,
I have created two global temporary tables like this -
Case 1-
postgres=# create global temp table foo(n int) *with
(on_c*ommit_delete_rows='true');
CREATE TABLE
Case 2-
postgres=# create global temp table bar1(n int) *on c*ommit delete rows;
CREATE TABLE
but if i try to do the same having only 'temp' keyword , Case 2 is
working fine but getting this error for case 1 -
postgres=# create temp table foo1(n int) with
(on_commit_delete_rows='true');
ERROR: regular table cannot specifie on_commit_delete_rows
postgres=#
postgres=# create temp table bar1(n int) on commit delete rows;
CREATE TABLE
i think this error message need to be more clear .
regards,
tushar

Hi All,
Please check the below findings on GTT.
_-- Scenario 1:_
Under "information_schema", We are not allowed to create
"temporary table", whereas we can CREATE/DROP "Global Temporary
Table", is it expected ?
It is ok for me. temporary tables should be created only in
proprietary schema. For GTT there is not risk of collision, so it can
be created in any schema where are necessary access rights.
Pavel
postgres=# create temporary table information_schema.temp1(c1 int);
ERROR: cannot create temporary relation in non-temporary schema
LINE 1: create temporary table information_schema.temp1(c1 int);
^
postgres=# create global temporary table
information_schema.temp1(c1 int);
CREATE TABLE
postgres=# drop table information_schema.temp1 ;
DROP TABLE
_-- Scenario 2:_
Here I am getting the same error message in both the below cases.
We may add a "global" keyword with GTT related error message.
postgres=# create global temporary table gtt1 (c1 int unique);
CREATE TABLE
postgres=# create temporary table tmp1 (c1 int unique);
CREATE TABLE
postgres=# create temporary table tmp2 (c1 int references gtt1(c1) );
ERROR: constraints on temporary tables may reference only
temporary tables
postgres=# create global temporary table gtt2 (c1 int references
tmp1(c1) );
ERROR: constraints on temporary tables may reference only
temporary tables
Thanks,

Hi,
I have started testing the "Global temporary table" feature,
That's great, I see hope.
from "gtt_v11-pg13.patch". Below is my findings:
-- session 1:
postgres=# create global temporary table gtt1(a int);
CREATE TABLE
-- seeeion 2:
postgres=# truncate gtt1 ;
ERROR: could not open file "base/13585/t3_16384": No
such file or directory
is it expected?
Oh ,this is a bug, I fixed it.
Thanks for the patch.
I have verified the same, Now the issue is resolved with v12
patch.
Kindly confirm the below scenario:
postgres=# create global temporary table gtt1 (c1 int unique);
CREATE TABLE
postgres=# create global temporary table gtt2 (c1 int
references gtt1(c1) );
ERROR: referenced relation "gtt1" is not a global temp table
postgres=# create table tab2 (c1 int references gtt1(c1) );
ERROR: referenced relation "gtt1" is not a global temp table
Thanks,
Prabhat Sahu
GTT supports foreign key constraints
in global_temporary_table_v13-pg13.patch
