People not backing up pg_xlog, deleting its contents, etc happens often
enough that I wonder if it should have a prominent 00_README or
00_WARNING_DONT_DELETE file created by initdb - or simply be renamed to
something scarier like "base_txrecords".
The annoyance of a readme is that it'd need translation.
People are used to logs being disposable. Anyone who's been responsible
for a database should ideally know better than to assume that
*transation* logs are disposable, but everyone has to learn sometime,
and not everybody does so by reading TFM (unfortunately).
