I believe the estimation is not far from the reality. I also am
interested in another country. My wild guess is, PostgreSQL popularity in
EU might be somewehre between Japan and US. In Russia it might be
between EU and Japan. Those says, the popularity rank might be:

Japan > Russia > EU > US

Of course these are just my guess...
