Hi,
I found that there is a situation that even when index only scan can be
effective,
the planner doesn't select this. The planner makes indexe paths in descending
order of indexrelid, and the new path is discarded if its cost is not less than
the existing paths' cost. As a result,

Hi,
In order to make changes to a shared buffer, one must hold a pin on it
and the content lock in exclusive mode. This rule seems to be
followed in most of the places but there are a few exceptions.
One can find several PageInit() calls with no content lock held. See,
for example:
$subject is broken:
create table prim (a int primary key);
create table partfk (a int references prim) partition by range (a);
create table partfk1 partition of partfk for values from (0) to (100);
create table partfk2 partition of partfk for values from (100) to (200);
You can't truncate prim

This appears to be the patch of record in this thread. I think there is
general desire for adding a setting like this, and the implementation is

Hi,
Why does the heap_page_item () of the pageinspect extension not consider
providing better user-friendliness?
My test table has the following data, and when I look at the t_data I see data
of type bytea instead of a more intuitive type, even the same type as the

What do you mean by "recovery time of specific backup"?
recovery time - is a time

I have implemented this. I didn't see any performance benefit using the

The reason that I wonder is that I surely add header file for the function.
In more detail,
I want to use TransactionIdEquals() function in freelist.c file.
Then, I
