IMHO, the first one means "run these programs, and pretend everything is
OK regardless of the outcome" while the second one means "if the
programs are available, they should run properly; if they are available
and fail, there is a problem that should be dealt with."

I really prefer the second approach for postinst. Note that the '2>&1'
is not necessary (and probably better left out, in order not to miss
really important error messages [I/O error, whatever]) with the 'which'
program that should be invoked by /bin/sh scripts with a standard PATH
(i.e., the one provided by debianutils).
