Use --enable-nls to turn it on; see installation instructions for details. See developer's guide how to make use of it in programs and how to add translations. psql sources have been almost fully prepared and an incomplete German translation has been provided. In the backend, only elog() calls are currently translatable, and the provided German translation file is more of a placeholder.
