Actually, there's a different bias here. Many, if not most, people who
install Postgres on Debian get it from other sources because the version
of Debian is old. Whereas people are more likely to install MySQL 5.1
and leave it alone, since Debian users are unlikely to be onboard with
the Oracle releases.
However, it is interesting that the number of MySQL installs on Debian
is still growing ... says that the demise of MySQL may be premature.
