Again, it was only the comparison chart that I was referring to.  As I
stated in a later posting, they actually recommend PostgreSQL for people
who want transactions, and that is a very gracious gesture on MySQL's
part.

The point I was trying to make was that the chart was promoted as being
an unbiased comparison, and I didn't think it was unbiased.  In fact,
they call it crashme, and in fact seem to avoid tests that crash MySQL,
while leaving in things that crash PostgreSQL.  Makes us look bad.

However, this is an old recollection, and I see on the current page that
this is no longer the case.  The current page looks much better, though
somehow you show PostgreSQL doesn't have HAVING or support -- comments.
However, I realize such a test is a major project, and you are not going
to get everything right.

Still, such comparisons are by nature biased.  If you have ten features,
and we have ten features, and we only have two features in common, a
biased comparison is going to show you has having ten features, and us
only having two features, with no mention of the eight features we have
that you don't have.

I actually find such charts to be fairly useless in most cases when
comparing cars, radios, etc.  I prefer a short paragraph summarizing the
major differences in the radios.
