Installing PostgreSQL on Oracle Solaris

Hi, ALL,
I tried to follow an instructions at
https://www.postgresql.org/ftp/binary/v9.6.1/solaris/solaris11/i386/
in the README but I received following:

[code]
igor@solaris:/usr$ sudo bunzip2 < postgresql-9.6.1-S11.i386-64.tar.bz2

And many other like those.

Is the instructions wrong?

I'm trying 9.6.1 because I'm using it on Windows/OSX for libpq.

Thank you.
