Pseudocode, as in
while (there is something to do)
process_one_item();
is a tool to write down an algorithm in a way that is easy for programmers to understand.
Pseudo-types, as in
https://www.postgresql.org/docs/current/datatype-pseudo.html
are something entirely different.
Here is a useful example:
CREATE FUNCTION successor(anyelement) RETURNS anyelement
LANGUAGE sql AS 'SELECT $1 + 1';
SELECT successor(41);
successor
-----------
42
(1 row)
SELECT successor(current_date);
successor
------------
2021-03-16
(1 row)
