Usage-statistic of documentation available?

Hello,

i want to translate the very fine documentation of PostgreSQL into
german. Like some others i already failed (more then one time).

Now i want to try a more pragmatic procedure. I'm heading to translate
the parts of the documentation which are read most at first.

Therefore i want to ask if there is a usage-statistic of the
documentation from postgresql.org (or at least some log files)?

Greetings from Germany,
