SQL is quite counter-intuitive to people who have only done
procedural programming.

Hi,
I have upgrade the postgres cluster from 9.5 to 9.6 using pg_upgarde
utility with -k option.
Now I just wanted to be confirmed that is it safe to run
delete_old_cluster.sh file as we have used -k option that must created
hard links with old cluster.
Suggestions are welcome.

SQL is only intuitive to people who've done programming... :)
Also, since your table names are only composed of lower case and
underscores, the double quotes are not needed.

With liberal usage of CTEs and subqueries writing a single SQL query should
be doable.

Thank you, David, with json_build_array() it works for a single query -
SELECT
JSONB_BUILD_ARRAY(
SUM(CASE WHEN (player1 = in_uid AND state1 = 'won') OR
(player2 = in_uid AND state2 = 'won') THEN 1 ELSE 0 END)::integer,

Ah right,
Thanks to those who responded. I have solved my problem by noting the advice to
use a select with order by. In particular, I need to export the data to a csv
file anyway, so I use the following copy command:

What would you tell pgadmin? "Order *this* *particular* query -- out of all
the billion queries I might write -- in *this particular* manner?"
No, that's not how things work. Just add an ORDER BY when you query the table.

Aggregate functions work on a single column to summarize many rows into
fewer rows. You seem to be wanting to combine multiple columns which would
be done by concatenation or array[column1,column2] or something like that.

Thanks Peter. The listing of the result is from pg-admin 4.30 using view/edit
data applied to the household_data table. In the past this has always returned
the table contents in the ORDR BY sort order. Do I need to specify some
preference in pg_admin to guarantee this?

Good evening,
In 13.2 I have 3 SQL queries, which work well and return integer values.
The values I feed to Google Charts (and currently I switch to Chart.js).
Currently I use the queries by calling 3 different custom stored functions
by my Java servlet.
I would like to convert the functions
What is your concern with it taking 20 hours vs 1 hour? Is this index
re-created on a regular basis?
Would it make any sense to materialize the value of foo(a,b,c) as a
generated column (PG12+ natively, or maintained by a trigger before)? Or
even bar(foo(a,b,c),geom)?
Do you know if

Thanks. Is there a free version of BDR?

Hi,
Need some advice here. I have an application using PostgreSQL. I need to
install it on 2 servers for redundancy purposes and have 2 databases. I
need the DBs to replicate to each other, in real-time. Writes can be done
on both DBs.
Please let me know if this is a feasible setup and the best

Hi all,
thanks for the feedback.
I was able to do it successfully but I didn't understand yet if there is a
bug in pg_hba.conf LDAP link interpretation or a messy domain.
So as I said previously, the ldapsearch is finding correctly the user1 fine
using only the url dc=company,dc=example,dc=com

Of course, otherwise the notion of "current database" wouldn't make
