if you like to have the latest version out a few days ago you can use the SlackBuild to build it yourself: download it from SlackBuild.org
http://slackbuilds.org/repository/14...em/postgresql/
read the README for necessary steps to take before launching the build, download
the latest tarball, change the VERSION to 9.3.2 in the postgresql.SlackBuild and launch the build; wait an handful of seconds/minutes and you're done.
for more informations on the build process, refer to the
general HOWTO.
