Oops, messed up my cut and paste, and forgot to double the quotes around
bytea%. This one I tested ;) to work fine:
select dblink_tok(t1.dblink_p,0) as f1, dblink_tok(t1.dblink_p,1) as f2
from (select dblink('hostaddr=127.0.0.1 port=5432 dbname=template1
user=postgres password=postgres','select proname, prosrc from pg_proc
WHERE proname LIKE ''bytea%''')
as dblink_p) as t1;
