Clearly MySQL should stop using their bug tracker so they won't have as many known crashing bugs!

Seriously though, I wouldn't be surprised if the Postgres guys were creating more reliable releases, but this is a really weak analysis.

I'd say both are bad. That makes comparing them pretty irrelevant.

MySQL: "We still have 20 known and tagged crashing and wrong result bugs"

pgSQL: "PostgreSQL does not have a bug-tracker."
