Documentation says you should use "elsif" rather than "elseif". In your
case everything between "return <38" and "else" is discarded as
unreachable code. The same sense will have function below:
create or replace function fubar() returns varchar as '
declare
l integer;
begin
l = 38;
if l < 38 then
return ''< 38'';
bleblbebleblebe sfdsdf;
nothing special;
else
return ''this is not possible'';
end if;
end;'
language 'plpgsql';
select fubar();
