  1. Add tests for inheritance trees mixing permanent and temporary relations

  1. Adding tests for inheritance trees with temporary tables

    Michael Paquier <michael@paquier.xyz> — 2018-06-19T02:21:31Z

    Hi all,

While look at the handling of temporary relations with partition trees,
I have noticed that there are no tests for inheritance trees with temp
tables.  This has been mentioned here:
https://www.postgresql.org/message-id/20180618060200.GG3721@paquier.xyz

Attached is a patch to close the gap.  That's of course not v11
material, so I am parking this patch into the next CF.

Thanks,

    Thanks. Some review comments here.

+create table inh_perm_parent (a1 int);
+create temp table inh_temp_parent (a1 int);
+create temp table inh_temp_child (a1 int) inherits (inh_perm_parent); -- ok
+NOTICE:  merging column "a1" with inherited definition

You could actually avoid this notice by changing create table statement like
create temp table inh_temp_child () inherits (inh_perm_parent);

+create table inh_perm_child (a1 int) inherits (inh_temp_parent); -- error
+ERROR:  cannot inherit from temporary relation "inh_temp_parent"
+create temp table inh_temp_child_2 (a1 int) inherits (inh_temp_parent); -- ok
+NOTICE:  merging column "a1" with inherited definition

Same suggestion as above.

+insert into inh_perm_parent values (1);
+insert into inh_temp_parent values (2);
+insert into inh_temp_child values (3);
+insert into inh_temp_child_2 values (4);
+select * from inh_perm_parent;
+ a1
+----
+  1
+  3
+(2 rows)
+
+select * from inh_temp_parent;
+ a1
+----
+  2
+  4
+(2 rows)

select tabloid::regclass will also print the name of the table where
the row resides. That will be useful to check where the rows come from
and also to test the inheritance children.

Okay, fixed.

Good point, I have added those.  Except that you meant
tableoid::regclass.
