Issue with Latest PostgreSQL Security Patch for Breezy

I strongly believe that the latest PostgreSQL security patch that I have installed from Ubuntu has slowed down PostgreSQL. It now takes an extra half-second to a second to display a result!

The patch was to block remote SQL injection or something like that, I think.

Anyone else seeing this? I have an 800Mhz with 256MB of RAM, so it amplifies slowness when it occurs. If you have a fast 3Ghz or something, you might not notice what I notice.
