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.
