 template1 │ jd    │ UTF8     │ en_US.UTF-8 │ en_US.UTF-8 │ =c/jd            ↵
           │       │          │             │             │ jd=CTc/jd
(3 rows)

template1=# \q
$

You can also run it with no command line provided:

$ eval `pifpaf run memcached`
$ env | grep PIFPAF
PIFPAF_PID=13387
PIFPAF_DAEMON=memcached
PIFPAF_URL=memcached://localhost:11212
PIFPAF_MEMCACHED_URL=memcached://localhost:11212
$ kill $PIFPAF_PID

Killing the daemon whose PID is contained in $PIFPAF_PID will stop the launched daemon and clean the test environment.

• PIFPAF_DAEMON which contains the name of the daemon launched

• PIFPAF_URL which contains the URL to the daemon
