PostgreSQL Calling File

Somebody asked: How do you run a script file from PostgreSQL’s psql prompt? I created two files to answer the question. Here are the two files:

Static File

SELECT 'Hello World!';

Dynamic File

SELECT 'Hello ['||current_user||']!';

It’s a simple solution, you put a \i or \include before the script file name, like:

\i helloworld.sql

It outputs:

   ?column?   
--------------
 Hello World!

or

\include hellowhom.sql

It outputs:

     ?column?     
------------------
 Hello [student]!

I hope this helps those trying to call SQL script files from an interactive psql session.
