Format output of postgres from psql

Format output of postgres – this is like \G in mysql

If you are looking for the \G equilvalent of the mysql in postgres, then here is what you are looking for:

On the psql terminal just do the following

\x auto;

This will prepare whatever you are going to display on the terminal to have the right output

here is an example of out formatted or nice output when you issue the command

infohub=# select * from help;
-[ RECORD 1 ]+--------------------------------------------------------------------------------------------------------------------------------------
id           | 1
date_created | 2018-08-18 09:58:54.774
message      | use \x auto command to get output printed nicely
title        | how to show the select output nicely formatted in psql
member_id    | 1
-[ RECORD 2 ]+--------------------------------------------------------------------------------------------------------------------------------------
id           | 2
date_created | 2018-08-18 10:41:46.979
message      | postgres has a nice output format option as well.
title        | An equivalent of \G nice format in mysql in postgres
member_id    | 1

As it can be seen above, the output is nice and easy to navigate than a bulky columns here and there.
