Its that way because :: is defined to make it that way.
3 has a type of integer
'3' has a type of text
::<type> is the PostgreSQL type casting operator that casts its left to to <type> (see the documentation I linked to)
So:
integer::text == text
cast(integer as text) == text
is the SQL Standard equivalent expression

integer::text == text, but which character 0x03 or 0x33 ?
Text should contain characters.
Characters is from character set.
Character 0x03 is valid in ASCII and UTF-8 character sets.
