hello,
it depends on SQL. plpgsql hasn't own arithmetic unit. You can test it simply:
postgres=# create or replace function a() returns bool as $$ begin
raise notice 'a'; return true; end$$ language plpgsql;
CREATE FUNCTION
postgres=# create or replace function b() returns bool as $$ begin
raise notice 'a'; return true; end$$ language plpgsql;
CREATE FUNCTION
postgres=# select a() or b();
NOTICE: a
?column?
----------
t
(1 row)
result: statements are short circuited.
