Call for translations

In anticipation of the release of PostgreSQL 9.3, it is once again time
to update the message translations. We are now in a string freeze, which has
traditionally been associated with the first release candidate, so it's a
good time to do this work now.

If you want to help, see <http://babel.postgresql.org/> for
instructions and other information. If there are already active
translation teams, please communicate with them first. The mailing list
<pgtranslation-translators(at)pgfoundry(dot)org> is available for general
discussion and coordination of translation activities.
