unfinished code

Describe the unexpected behaviour

LIMIT clause has no effect on executable

select * from executable('myscript', 'TabSeparated', 'value String')
limit 100

execution time is the same with or without LIMIT clause

Expected behavior

Child process should be killed once LIMIT is reached (limit 100 should act like head -n 100)

Agree, we can close the pipe if limit is reached.
