Try this:

 

SELECT regexp_matches('foobar beque bazil barf bonk', '(\\m.)', 'g')

 

Now you have the first letters, you can use array_to_string to get an string and use concat_str after this:

If you are sure that your words are space delimited, you may use this:

select regexp_replace('Ispahani Public School'||' ', '([^ ])([^ ]* )',
'\\1', 'g');
