If you want to do a fair estimation of space saving, you also have to take
into account the size of the dependencies for each back-end.

To get an idea, I ran `pacman -S postfix` in a clean chroot, and the result
is 41.36 MB of extra disk usage (ignoring the package cache), 36.26 MB of
which is for different backends (pcre and sqlite were already pulled in by
the base package). Whether that space matters or not depends on a lot of
things, but I think its nice that you can avoid pulling in unnecessary

So thank you David!

Kind regards,

sudo pacman -r root -S postfix
