How To

Setup psql

$ sudo dnf install postgresql postgresql-server # install client/server
$ sudo postgresql-setup initdb                  # initialize PG cluster
$ sudo systemctl start postgresql               # start cluster
$ sudo -iu postgres				# login as postgres
$ psql						# enter psql

Create a db, and connect to it.

CREATE DATABASE orlab1;
\c orlab1

Create a table and add data

Export to CSV

First export to /tmp, and copy to working directory.

COPY distribucije_linuxa TO '/tmp/distribucije_linuxa.csv' DELIMITER ',' CSV HEADER;
cp /tmp/distribucije_linuxa.csv .

Export to JSON

SELECT array_to_json(array_agg(row_to_json (r))) FROM (SELECT * FROM distribucije_linuxa) r;

Copy output and paste it in distribucije_linuxa.json.

Pretty print using Python

cat distribucije_linuxa.json| python -m json.tool > distribucije_linuxa_pretty_print.json

Dump db

pg_dump orlab1 > /tmp/orlab1.sql
cp /tmp/orlab1.sql .

Added support for child parent as json with a function

CREATE OR REPLACE FUNCTION r(dist TEXT) RETURNS JSONB AS
$$
BEGIN
RETURN json_build_object( 
'name',
  array(SELECT developername FROM originaldevelopers WHERE distributionname = dist));
END;
$$ LANGUAGE PLPGSQL;

to query:

SELECT d.distributionname, d.basename, d.releasetype, d.packagemanager, d.supportedarch, d.yearofcreation, d.homepage, d.distrowatchrank, d.targetuse, d.wikipage, r(distributionname) AS od FROM distribucije_linuxa AS d NATURAL JOIN originaldevelopers GROUP BY od, d.distributionname, d.basename, d.releasetype, d.packagemanager, d.supportedarch, d.yearofcreation, d.homepage, d.distrowatchrank, d.targetuse, d.wikipage;```
