Hi, We are seeing some overall performance degradation in our application since we installed the security release. Other commits were also done at the same time in the application so we don't know yet if the degradation has any relationship with the security release. While we are digging into this, I would like to know if it is possible that the release has some impact on performance. After reading this "It was created as a side effect of a refactoring effort to make establishing new connections to a PostgreSQL server faster, and the associated code more maintainable.", I am thinking it is quite possible.
I doubt that particular commit, the one that fixed the security issue, could cause any meaningful slowdown. But it's not impossible that some other fix included in the release would cause a regression, although we try to be careful to avoid that. If you narrow the culprit down to the new PostgreSQL version, we're going to need more details to find the root cause.
