Hi,
After seeing the below, I feel partitioning is not working properly or
it maybe case that my understanding is wrong. Can somebody explain me what
is happening?
postgres=# create table busbar_version (objectid int, ver_id int) partition
by hash(ver_id);

I concur with Laurenz's diagnosis that you need to use an indicator

The problem is, one can't test that and get a reliable answer, becau
We got the following from one of our NetApp contacts regarding a similar

Hi all,
I'm just wondering if there is a way to discriminate a connection
opened from an application server from one opened by an interactive

I have a table t, with just two columns, an `id SERIAL` and a `record

Each `record` column jsonb has about 40 json key-values, of which
about 10 are nested fields.

Hi!
What is difference between following error messages?
ERROR: canceling statement due to conflict with recovery
FATAL: terminating connection due to conflict with recovery
I tried to correlate process termination on standby and vacuuming on master.
