What Postgres version?

In version 12 and 14 I get:

select initcap('notemachine');
initcap
-------------
Notemachine

select initcap('Sainsbury''s Bank');
initcap
------------------
Sainsbury'S Bank

Which follows the definition here:

https://www.postgresql.org/docs/14/functions-string.html

initcap ( text ) → text

Converts the first letter of each word to upper case and the rest to
lower case. Words are sequences of alphanumeric characters separated by
non-alphanumeric characters.

What is the encoding, collate, ctype for the database?

Can be found in psql using:

\l db_name
