Good idea. But just a little correction, use `sort` or else `uniq`
will not work properly:

find /usr/bin -type f -exec pkgfile '{}' ';' | sort | uniq

or use only | sort -u instead

In a slim install, you're unlikely to have lost much due to the nature
of /var (only variable data, aka no installed files). If you had a
database on disk you did lose that, eg postgres. Also firewall rules
and all logs.

Try pacman -Ql | grep /var to see what owns stuff in there.

 Hello,

 I've lost content of /var, other partitions are ok, so system somewhat

Or better, check with the command that tests all packages' files for presence.

# pacman -Qk | grep -v '0 missing files'

LOL. Where do you think that information is stored? I'll give you a
subtle hint: It's /var.

OP is basically screwed. There is no easy way to get his stuff back into
working order. There is not even an easy way to determine which packages
have been installed.

Do you mean `pacman -S $(pacman -Qq)`?

You can install a fresh install on top of the old install by using
`pacstrap`. I would boot up a live cd, move /etc to /etc_old, then
remove all other top levels directories other than /home, and install
again with pacstrap. The pacman database was in /var so there's little
point in trying to reinstall the same packages, and it doesn't seem very
important anyway - you'll remember what you used when it's missing, and
it's trivial to install it again.

If you have enough time, I would try using pkgfile to recover the
installed packages. I thing something like this should suffice:
# update the pkgfile database
pkgfile -u
# find the package names for all binaries
find /usr/bin -type f -exec pkgfile '{}' ';' | uniq

I assume that the libs would be installed as depends for the programs
that has a binary in /usr/bin
