It does not seem to be finding the \n delimiter:  (I've also tried \r with the same result)

lcd1_dev=>   select * from
lcd1_dev->   (select proname, unnest(string_to_array(prosrc, '\n')) as l from pg_proc) ss
lcd1_dev-> where l ~* 'ypoi_db';
     proname     |                                                                             l

You mean you just want part of each prosrc entry?  Try something like

select * from
  (select proname, unnest(string_to_array(prosrc, '\n')) as l from pg_proc) ss
where l ~* 'ypoi_db';
