And then there are the people that would like to upgrade and get a performance gain without having to change their programs. A simple conf flag could turn query/plan caching off for all those that rely on each statement being re-planned. This is where SQLServer etc. tend to get big wins. I know from direct comparisons that SQLServer often takes quite a bit longer to parse/plan a select statement than Postgres, but wins out overall from its query/plan caching.
