No - I mean when each row of pr (contain) has 'ip' inserted as a value or
data.

Sample 2 below, does not work. From a logical (perhaps naive) extension

do this as part of the database structure _not_ as data retrieval.
Could someone explain to me why this isn't acceptable as a simple basic
function?
Could someone explain to me what needs to be changed, enhanced or
modified to make this database structure work?
Sample 2
create or replace function base() returns trigger as $$
begin
insert into pi (fluid_id) values (new.fluid_id)
where pr (contain) = 'ip';
I suppose you mean "where pr.contain = 'ip'" instead? pr is a table, not a
function.
You'd be in some interesting trouble if there'd be a function pr(text)
returning text - it would evaluate the function with the content of your
column and compare the result to your string.
